Selling & Trade-Ins
Private sale, dealer trade-in, or an instant online offer — each pays differently, costs you differently in time and hassle, and suits a different kind of car. Here's how to work out which one is actually right for yours.
Every car in New Zealand eventually gets sold, and everyone who sells one asks the same question: do I sell it myself, hand it to a dealer as a trade-in, or take one of the instant online offers that have become common in the last few years? There's no single right answer — it genuinely depends on your car, your timeline, and how much hassle you're willing to absorb for a better number. What follows is a straight comparison of all three, without pretending one option is secretly best for everyone.
Almost every sale in New Zealand falls into one of three categories. Understanding what's actually happening behind each one — who's taking the risk, and where the margin goes — makes it much easier to judge whether an offer is fair.
You list the car yourself — Trade Me Motors, Facebook Marketplace, or word of mouth — deal directly with buyers, and keep the full sale price minus whatever it cost you to list, present and negotiate the car. Private sale is the route most likely to get you the highest headline number, because there's no dealer margin sitting between what a buyer pays and what you receive. The trade-off is that you're doing all the work: photographing the car, answering messages, hosting test drives with strangers, negotiating one-on-one, and handling the paperwork and payment yourself.
You bring your car to a dealer, usually as part of buying another vehicle from them, and they give you a single trade-in figure that's deducted from the price of your next car. The dealer then takes on the reconditioning, advertising, storage and resale risk — including the risk that the car takes months to move or needs unexpected work before it can go back on the lot. That risk is why a trade-in figure is almost always lower than what the same car could fetch privately: you're effectively paying the dealer to take the whole process off your hands in a single transaction.
A newer middle option: you enter your car's details online, get an indicative number within minutes, and — if you go ahead — a firm offer after a quick inspection, often with same-day payment. It sits between the other two: faster and less effort than a private sale, but usually a better number than a generic trade-in because the buyer isn't tying your payout to the price of a car you're buying from them. LUSKI runs one of these — our Sell Your Car tool gives you an indicative number on the spot with no obligation to accept it.
| Route | Typical payout | Time to cash | Effort required |
|---|---|---|---|
| Private sale | Highest — full market value minus your costs | Days to several weeks, unpredictable | High — listing, viewings, negotiation, paperwork |
| Dealer trade-in | Lowest of the three, bundled into a new purchase | Same day, tied to buying another car | Low — one conversation, one number |
| Instant offer | Middle ground, standalone cash offer | Same day to a few days | Low — online form plus a quick inspection |
Whichever route you take, the same handful of factors decide what your car is actually worth on the day:
The headline number from a private sale looks better on paper, but it rarely accounts for everything that goes into getting there.
Listing a car privately isn't free — premium Trade Me listings, photography, and any reconditioning you do to make the car presentable all come out of your eventual proceeds. Then there's time: responding to messages, filtering out tyre-kickers and lowball offers, and coordinating viewings around your schedule. Meeting strangers to hand over a car and a large sum of cash also carries a real safety consideration — arranging to meet in a public place, during daylight, and confirming payment has actually cleared before handing over keys are basic precautions worth taking seriously.
There's also a legal distinction worth understanding: when a registered dealer sells you a car, protections under the Consumer Guarantees Act generally apply, giving you recourse if something significant goes wrong soon after purchase. Private sales between individuals don't carry the same guarantees — which is exactly why some buyers will negotiate harder or walk away from a private listing entirely, and it's a factor that quietly shapes what your car is genuinely worth to a private buyer versus a dealer.
The best number on paper isn't always the best deal once your time, effort and risk are actually priced in.
There's no universal answer, but there is a reasonably reliable way to think about it:
Cars that are unusual, high-value, or performance-oriented are also worth a specific mention. These tend to attract a smaller, more knowledgeable pool of private buyers who know exactly what the car should be worth, which can work in your favour if you're patient — but it also means a longer wait for the right buyer to show up. If you're weighing that decision on a modified or import performance car specifically, our guide to buying a used performance car in NZ covers the same condition and history factors from the buyer's side, which is worth understanding before you price your own car.
A handful of habits improve your outcome no matter which of the three routes you choose.
Get multiple numbers before committing to anything. A trade-in offer from one dealer, an instant offer, and a rough sense of private-sale value from comparable listings together give you a genuine picture of where your car sits — and leverage if a first offer feels light. Gather your paperwork in advance: service records, the original purchase agreement, and any receipts for recent work all speed up the process and tend to support a better number, since they remove a buyer's or dealer's uncertainty. A basic detail and a current Warrant of Fitness also go a long way — a lapsed WOF is one of the most common reasons an on-the-spot offer gets discounted, simply because it becomes the buyer's problem to sort first.
If you're weighing a trade-in specifically, ask the dealer to break the deal into two separate numbers: what they're paying for your car, and what they're charging for the one you're buying. A dealer unwilling to separate those two figures is usually one worth being cautious of, since bundling them is the easiest way to make a mediocre trade-in look acceptable inside an apparently strong purchase price. It's a principle we apply ourselves — every trade-in through LUSKI's dealership is quoted as its own clear figure, separate from anything you're buying from us.
We run both sides of this equation. Our Sell Your Car tool gives you an instant, no-obligation indicative valuation in a couple of minutes, followed by a same-day firm offer if you want to go ahead — no pressure to buy anything else from us in the process. If you'd rather see it from the other direction, browse our current inventory to get a feel for how we price and present cars once they're ready for resale, or read why we started LUSKI if you want the fuller story behind how we do business.
The questions we get asked most often about selling and trading in.
Is a dealer trade-in always worth less than a private sale?
Usually, but not always. A trade-in typically pays less than a well-run private sale because the dealer has to cover reconditioning, advertising, holding costs and margin before it goes back on the lot. But once you factor in the time a private sale takes, the cost of getting the car presentable, and the risk of a deal falling through, the gap is often smaller than people expect — especially on cars that need work to sell privately.
How fast can I actually sell my car in NZ?
A dealer trade-in or instant offer can be done same-day once you've got the paperwork sorted. A private sale is far less predictable — desirable models in good condition can sell within a week, while less common cars or anything priced optimistically can sit for a month or more with ongoing listing renewals and viewings to manage.
Do I need a Vehicle Inspection Certificate or WOF to sell my car privately?
Your car doesn't need a current WOF to be sold privately, but most buyers will ask about it and a lapsed WOF is a common reason offers get lowered on the spot. It's worth getting a current WOF before listing if yours has expired or is close to it, since it removes an easy objection and signals the car has been looked after.
Will trading in my car affect what I pay for the next one?
It shouldn't, if the dealer is running an honest deal — the trade-in value and the price of the car you're buying should be two separate, clearly stated numbers. Be wary of any dealer who won't break the deal down into those two figures separately, since bundling them together is the easiest way to hide a weak trade-in offer inside an apparently good purchase price.
