The register search
Against the serial or VIN number rather than the seller’s name. A registered interest attaches to the machine, so this is the check with the largest consequence.
Guide
Dealer or private, and what changes.
The private sale is cheaper and carries every risk the dealer would otherwise absorb. Which is the better purchase depends on which of those the buyer is equipped to handle.

The short version
What the price difference is buying.
- Private is cheaper for reasons. The gap covers warranty, preparation, title assurance and somebody who is still there next month, not only a margin.
- Finance is available on both. Private sales are financed routinely. What differs is that settlement has to be arranged so an existing interest is cleared at transfer.
- The register search matters far more privately. A dealer normally has clear title. A private seller may have finance owing, and the interest follows the machine rather than them.
- Trade-ins only work at a dealer. Where an outgoing machine still carries finance, a dealer trade handles the settlement as part of the transaction. A private sale leaves that to the seller.
The comparison
What differs between the two routes.
General positions rather than universal rules, since dealers vary and some private sellers are meticulous. The shape holds even where individual cases do not.
| Dealer | Private sale | Auction | |
|---|---|---|---|
| Price | Higher | Lower | Variable, sometimes lowest |
| Warranty | Commonly some cover | Usually none | None |
| Title assurance | Normally warranted | The buyer’s problem | Depends on the terms of sale |
| Machine preparation | Usually checked and serviced | As it stands | As it stands, often unseen running |
| Inspection before purchase | Straightforward to arrange | Depends on the seller | Limited viewing window |
| Trade-in accepted | Yes, including settling finance | No | No |
| Recourse if something is wrong | A business that is still there | An individual, and whatever they are worth | Usually none under the terms |
| Finance | Straightforward, sometimes in-house | Routine, with settlement arranged | Possible, and timing is tight |
General differences between purchase routes for used equipment in New Zealand.
The trade
What the buyer takes on.
Buying from a dealer
Paying for someone else to have checked.
A dealer has taken the machine in, formed a view on it, prepared it and put its name behind it. Some of the price difference is margin and a real part of it is work that would otherwise fall to the buyer, plus a warranty on a used machine that has genuine value on equipment where a major failure is expensive.
The other thing a dealer provides is continuity. If something is wrong in three months there is a business to talk to, and a business that wants to sell the next machine as well. That is worth more on complex equipment than on a trailer.
A dealer is also the only route where a trade-in works, which matters enormously where the outgoing machine still carries finance. The dealer settles the existing facility as part of the transaction rather than leaving the buyer to unwind it.
Buying privately
Doing the work and keeping the difference.
A private purchase is cheaper and every check that a dealer would have done falls to the buyer. The register search, an independent inspection, verification of service records and confirmation that the seller can actually sell the machine are all the buyer’s responsibility, and each is cheap relative to the saving.
The risk that has no cheap mitigation is the absence of recourse. If a major component fails a month later there is nobody to go back to, and if the seller misrepresented the machine, whatever claim exists is worth what the seller is worth.
Private purchases are financed routinely, and the one thing that must be arranged is settlement. Payment routed through the financier lets any existing interest be paid out and discharged at the moment title transfers, which is the arrangement that makes a private purchase safe.
Doing it properly

Each of these is inexpensive relative to the machine and expensive to skip. Written as observations of what careful buyers do rather than as instructions.
02
Evidence the seller can sell it
Purchase invoice, finance discharge or company records where a business is selling. A clean register result does not prove ownership on its own.
03
An independent inspection
On higher-value plant particularly, covering the expensive components rather than overall appearance. Cheap relative to a hydraulic or transmission failure.
04
Service records
Documented servicing is worth real money at valuation and is the strongest available signal on how a machine has been treated.
05
Certification status
On vehicles and trailers, current certification affects both whether the machine can work and what it is worth. Restoring lapsed certification is the buyer’s cost.
06
Settlement routed through a financier
The arrangement that clears any existing interest at transfer. A seller unwilling to allow it is worth pausing over, because it costs an honest seller nothing.
Where trade-ins change the answer
An outgoing machine with finance owing needs a dealer.
Where the machine being replaced still carries a facility, a dealer trade handles the settlement inside the transaction: the trade value clears the balance and any surplus becomes the deposit on the replacement. A private sale of that same outgoing machine leaves the seller to obtain a payout figure, settle the facility and arrange for the buyer’s payment to clear it at transfer, which is entirely possible and is more work and more risk. That single practical difference is frequently what decides the route, quite separately from the price comparison on the incoming machine.
Worked scenarios
Three purchases, three routes.
Illustrative scenarios on stated assumptions, showing how the right route depends on the buyer rather than on the machine.
A mechanically capable contractor buying a trailer
The private purchase that works
The buyer knows the equipment, obtains the chassis number, searches the register, inspects the unit themselves and arranges settlement through a financier.
On these assumptions a $55,000 amount financed at an indicative 12% over 42 months carries a repayment near $415 a week. The saving against dealer pricing is real, and the buyer earned it by doing the work a dealer would otherwise have done.

The dealer purchase that is worth the premium
The business has no backup capacity, so a failure stops it entirely. It buys from a dealer with a warranty and a service relationship, at a price above the private market.
In this scenario the premium is buying protection against a risk the business cannot absorb, which makes it the cheaper purchase rather than the dearer one. The comparison that matters is not the two prices; it is the price gap against the cost of a stopped business.

Replacing a machine that still carries finance
The trade-in that decides the route
The outgoing machine has a balance owing and the incoming machine is available both privately and from a dealer, with the private option cheaper.
In this scenario the dealer route wins on total effort and risk, because the trade settles the existing facility inside the transaction and any surplus becomes the deposit. The private route would require the buyer to sell the old machine themselves, obtain a payout figure and coordinate two settlements. Both are possible and only one of them is simple.

The margin question
What a dealer does between taking a machine in and selling it.
The dealer premium reads as margin and is partly something else. A machine taken in on trade is inspected, and whatever that inspection finds is either repaired or reflected in the price. It is cleaned and presented, which affects nothing mechanical and a great deal about what a buyer can see. Its title is established, its finance is settled and its registration is dealt with. Where there is a warranty, the dealer is pricing the risk it has just taken on by offering one.
None of that is free and all of it would otherwise fall to the buyer, which is the honest way to read the gap. A capable buyer who inspects competently, searches the register, verifies title and accepts the risk is genuinely doing the dealer’s work and is entitled to the dealer’s margin. A buyer who does none of those is not saving money; they are buying an unknown machine at a discount that may or may not cover what they have not checked.
There is one further asymmetry that has nothing to do with the machine. A dealer wants to sell the next one too, and that continuing interest is worth something when a problem appears three months later. A private seller has no such interest and, quite reasonably, has moved on.
Auctions
The third route, and why it prices where it does.
Auctions sit below both dealer and private pricing for reasons that are visible in the terms of sale. Viewing windows are short, machines are frequently not run under load, condition reports vary from thorough to nominal, and recourse after the fall of the hammer is commonly limited or excluded entirely. The price reflects all of that rather than representing a market inefficiency.
They suit a buyer who knows the class of equipment well enough to form a view from a short inspection, who can absorb a poor outcome without it mattering, and who has arranged finance in advance because settlement timeframes are short. That combination describes an experienced trade buyer more often than it describes a business buying its first machine.
Where an auction is being considered, the terms of sale are the document that matters, and reading them before bidding rather than after is what separates a calculated risk from an assumed one. Some auctioneers publish register search results and some do not, and verifying rather than assuming is the safer position at a clearing sale where machines come from many vendors.
Timing
How the route changes the pace of a purchase.
A dealer purchase moves at the pace of the finance, because everything else is already in order. Title is clear, the machine has been prepared and the dealer is used to settling through a financier, so once an approval exists the transaction completes quickly.
A private purchase adds steps that are individually small and collectively slower. The serial number has to be obtained, the register searched, evidence of title produced, an inspection arranged if one is being done, and a payout figure sought where an interest exists. None of that takes long and it takes coordination, and a private seller who wants cash today is frequently not willing to wait for it.
That pressure is worth recognising for what it is. A seller pushing for immediate payment on a machine that has not been searched is asking the buyer to carry a risk in exchange for the seller’s convenience. Where a machine is genuinely worth buying, a seller who is genuinely entitled to sell it loses nothing by waiting two days.

FAQ
Questions, answered
Is a private sale always cheaper?
Usually on the headline price, and not always overall. The gap covers warranty, preparation, title assurance and recourse, all of which have value that varies with the buyer. On a machine a business cannot afford to have stop, the dealer premium is frequently the cheaper purchase once downtime is priced honestly.
Can a private purchase be financed?
Routinely. What differs is settlement: payment is normally routed through the financier so any existing registered interest can be paid out and discharged at the moment title transfers. That arrangement is what makes a private purchase safe, and a seller unwilling to allow it is worth pausing over.
Why does the register search matter more privately?
Because a dealer normally holds clear title while a private seller may still have finance owing. A registered security interest attaches to the machine rather than to the seller, so a buyer who pays in full can lose the machine to a financier who was never paid. The search is inexpensive and takes minutes.
Does buying from a dealer guarantee clear title?
A reputable dealer will normally warrant it and a search still costs almost nothing. The practical difference is that if something is wrong there is a business with a reputation and a continuing interest in the buyer, which is not true of a private seller who has moved on.
Can a trade-in be used on a private purchase?
No. A trade-in only works at a dealer, and that matters most where the outgoing machine still carries finance, because a dealer settles the existing facility inside the transaction. Privately, the seller has to obtain a payout figure and coordinate the settlement themselves.
What warranty comes with used equipment from a dealer?
It varies considerably by dealer, by machine and by age, from the balance of a manufacturer warranty on near-new equipment through to a limited dealer warranty on older stock. It is worth reading rather than assuming, because the scope and the exclusions differ more than the headline does.
Is an auction purchase riskier than a private one?
Frequently, because viewing windows are short, machines are often not run under load, and the terms of sale commonly limit recourse considerably. The prices reflect that. An auction suits a buyer who knows the equipment well and can absorb a bad outcome, rather than one buying their first machine.
Should an inspection be arranged on a private purchase?
On higher-value plant it is cheap relative to what it protects against, and it covers the expensive components rather than overall appearance. On simpler equipment such as a trailer, a capable buyer’s own inspection is frequently sufficient. The value of an independent report rises with the complexity of the machine.
What if a private seller cannot produce a purchase invoice?
It is worth understanding why before proceeding. A clean register search does not prove ownership, and the combination of no documentation and no registered interest is not the same as clear title. Company records, a discharge notice or a prior invoice all help establish the position.
Does GST work differently on a private sale?
It can. A GST-registered seller charges GST and a private, non-registered seller does not, which affects what a GST-registered buyer can claim. That is a question about the specific transaction and it is one the accountant is the right person to settle before the price is agreed rather than after.
How much cheaper is private, typically?
It varies by class of equipment, by condition and by how motivated the seller is, and any single figure would be misleading. The more useful approach is to run both prices through a repayment calculation at the same term and rate, because the weekly difference is usually smaller than the price gap suggests.
How much slower is a private purchase?
Days rather than weeks, and the steps are individually small: obtaining the serial number, searching the register, confirming title, arranging an inspection and obtaining a payout figure where an interest exists. A seller pressing for immediate payment on an unsearched machine is asking the buyer to carry a risk for the seller’s convenience.
Do dealers finance their own used stock?
Many do, through an arrangement with a financier or occasionally in-house, and it is convenient. It is worth comparing against an independent quote on total cost rather than accepting on convenience, because a rate that looks similar can carry different fees, and the machine and the finance are separate decisions even where they arrive together.
Which route suits a first machine purchase?
A dealer more often, because the checks a buyer is least equipped to do are precisely the ones a dealer has already done, and because there is somebody to go back to. A buyer who knows the equipment well and has done the checks before is in a much better position to take the private saving.
