A “we buy cars” offer gives you a straightforward way to sell, but the amount quoted only makes sense when compared with what you could realistically receive elsewhere. Start by estimating your car’s likely private-sale price, then subtract the costs and effort involved in preparing, advertising and handing it over. Compare that net figure with the buyer’s final offer, not an early estimate that may change after an inspection. A direct sale may be worthwhile even if it brings in less, especially when you value a quick, simpler transaction. The aim is to understand the trade-off before you accept.
A business advertising “we buy cars” may offer to purchase your vehicle directly, sometimes after an online valuation or an in-person inspection. The main appeal is convenience: you may avoid creating a listing, arranging viewings and negotiating with individual buyers. The exact process differs between providers, so check whether the business is buying the car itself or acting as an intermediary.
A direct buyer needs to account for its own costs and risks, which may include preparing the car for resale, holding it and finding a future buyer. For that reason, its offer may be below the price a private seller hopes to achieve. That difference is not automatically evidence of an unfair offer. It is the amount you should weigh against the time, expense and uncertainty of selling independently.
Also distinguish an initial estimate from a confirmed offer. An online figure may rely on the details you enter, while a later inspection can reveal issues that affect the amount. Ask what could change the quote, whether you are free to decline the revised amount, and whether any fees apply if you do.
Before judging an offer, build a sensible estimate rather than relying on one high listing or a general valuation. The goal is not to predict the exact amount a buyer will pay. It is to create a reasonable range for a private sale of a car in similar condition.

For example, a car with the same model year but a different engine, trim or substantially different mileage may not be a useful comparison. A well-presented listing with detailed service records is also not directly comparable to a vehicle with known faults. Note the differences instead of treating every similar-looking car as a price match.
| Selling route | What to compare | Main advantage | Main limitation |
|---|---|---|---|
| Direct “we buy cars” sale | Final offer, possible deductions, payment timing and collection arrangements | Can reduce the work of advertising and meeting prospective buyers | The offer may be lower than a successful private sale, and an estimate may change after inspection |
| Private sale | Likely sale price minus preparation, advertising and transaction costs | You control the listing and may achieve a higher gross price | You handle enquiries, viewings, negotiation and the risk of delays or a sale falling through |
| Trade-in with another vehicle purchase | The changeover amount and the separate purchase price of the next car | Can combine selling and buying in one transaction | A high trade-in figure alone does not show whether the overall deal is good |
For a trade-in, compare the amount you need to pay to change cars, not just the value assigned to your current vehicle. A generous-looking trade-in figure can be offset by a less favourable price on the next car. Ask for the figures separately so you can assess the whole transaction.

Use a simple comparison: estimate your likely private-sale proceeds, subtract any selling costs, and compare the result with the direct buyer’s confirmed offer. Include only costs you expect to incur. These might include advertising or listing charges, agreed repairs, cleaning or detailing, and other expenses you would not otherwise pay.
Be cautious about spending money to improve the car before selling. A repair may make the vehicle easier to sell, but it may not increase the offer by as much as it costs. If a fault is likely to concern buyers, get a clear repair estimate and ask whether fixing it would materially change the buyer’s valuation. You can also compare the direct offer as-is with the likely private-sale outcome as-is.
Time is a separate consideration rather than a bill you must subtract. You could estimate how many hours you expect to spend preparing the car, answering enquiries, arranging viewings and completing the sale. If you want to place a personal value on that time, include it as a decision aid, but keep it separate from cash expenses. That makes the comparison clearer: one figure is expected money, the other is the convenience you receive.
Ask the buyer to explain the offer in writing and confirm the conditions attached to it. A useful quote should make clear whether the amount depends on inspection, whether collection is included, how and when payment will be made, and what paperwork each side must complete. Do not assume that an online estimate is a guaranteed purchase price.

If the buyer revises the amount after inspection, compare that new figure with your private-sale estimate again. You do not have to treat the original quote as the benchmark once the terms have changed. If you feel pressured to accept immediately, pause and review the written offer before making a decision.
A private sale may suit you if comparable cars support a higher achievable price, the vehicle is presentable, and you have the time to manage the process. It can also make sense when you are comfortable answering detailed questions and arranging viewings. The potential benefit is a higher amount before costs; the limitation is that it may take longer, and the final buyer may negotiate.
Prepare an honest listing with clear photographs and a factual description. Include the vehicle’s condition, service information, known issues and any relevant inspection or registration details. Accurate information can help filter out unsuitable enquiries and reduce the chance of disagreement later.
Plan viewings carefully. Decide in advance what information you will share, how you will handle test-drive requests and what payment arrangements you will accept. Keep the vehicle secure, do not hand over keys or documents before the sale is agreed, and confirm that payment has been received before completing the handover. If you are selling in New Zealand, check NZTA’s current seller notification and change-of-registered-person process and complete the required steps.
A direct sale may be the better fit when you need a predictable handover, have limited time, or do not want to manage multiple enquiries and viewings. It may also be practical if the car needs work and you would rather not arrange repairs before selling. The convenience has value, but decide how much lower an offer you would accept before you start negotiating.
It is especially important to compare the final amount when the vehicle has faults or an uncertain service history. A private buyer may be harder to find, and repair costs could reduce your proceeds. On the other hand, do not assume that a direct buyer’s first estimate is automatically the strongest available offer. If time allows, compare more than one written offer and check that each is based on the same vehicle details and condition.

They may be lower than the price a private seller could achieve because a direct buyer has costs and resale risks to consider. The difference varies with the car, its condition and the offer terms, so compare a final offer with a realistic private-sale estimate rather than assuming either route will pay more.
Not unless the provider clearly confirms that it is binding and explains any conditions. Many estimates depend on the vehicle details supplied and may be revised after an inspection. Ask what could change the amount before arranging the sale.
Compare listings for vehicles that closely match yours in year, variant, mileage and condition, then adjust for differences such as faults, service records and presentation. Remember that asking prices are not proof of completed sale prices, and allow for negotiation and selling costs.
Not automatically. Compare the repair cost with the likely change in the offer, and consider whether the repair would also make a private sale easier. If the numbers are uncertain, request an as-is offer and compare it with a repair estimate before committing.
Ask your lender for the current payout information and confirm how the proposed buyer would handle settlement. Compare the offer with the amount needed to clear the finance, since the cash left over may be less than the headline purchase price—or there may be a shortfall to address.
Judge a “we buy cars” offer against the amount you could realistically keep from a private sale, not against an optimistic listing price. Get the direct buyer’s conditions in writing, account for selling costs and decide how much the simpler handover is worth to you. If the offer meets your needs after that comparison, convenience can be a sound reason to accept; if it does not, a private sale or another written offer may be worth pursuing.
