How to Negotiate a Used Car Price
The buyer who does their homework and is willing to walk away will always get a better deal. Here's the exact process.
The single most important rule
Know your walk-away price before you open a negotiation. A buyer who hasn't decided on a maximum will pay more every time. Calculate it before you call or visit — then stick to it.
1Set your walk-away price before first contact
Use the DBB decision tool or check comparable listings on Autotrader, CarGurus, and Cars.com to find the real market range for this exact year, mileage, and trim. Note the low, average, and high prices.
Your walk-away price should be the fair market value minus any known issues. If the car has an open recall, factor in the inconvenience. If it needs new tyres ($400–$800), take that off the top. If the inspection found brake pads at 20%, deduct the replacement cost.
2Make an opening offer 10–15% below asking
Never offer the asking price first. Open 10–15% below asking — more if you have concrete issues from an inspection report. This gives you room to move up while the seller moves down, and you meet somewhere in the middle.
Always lead with specifics, not just a number. Vague low-balls get dismissed; reasoned offers get counter-offers.
3Respond to counter-offers strategically
When the seller counters, don't immediately split the difference. Pause. Say “Let me think about that.” Then come back with a number that is closer to the middle, but still below their counter. You're trying to land at or below your walk-away price, not their asking price.
If they don't budge on price, ask for inclusions instead: full tank of fuel, fresh MOT, new tyre, a year's warranty, or the cost of the first service included. These often cost sellers less than the cash discount they won't give you.
Never let a counter-offer pressure you to exceed your walk-away price. Say: “I appreciate it, but that's above what I can justify for this car at this mileage. I'm going to have to pass — thanks for your time.”Then actually start to leave. This frequently produces the best offer.

Frequently Asked Questions
How much can you typically negotiate off a used car?▾
On private listings: 5–15% below asking is realistic, especially if the car has been listed for a while. On dealer listings: 3–10% is more typical because dealers already build in less margin on used cars than new ones. Cars with documented issues (from a mechanic report) or open recalls give you more leverage for larger discounts.
Should I negotiate by email, phone, or in person?▾
Email or text is ideal for initial anchoring — you can take your time, present data, and avoid pressure tactics. Save the in-person visit for the test drive and final negotiation, where your willingness to actually walk out has real impact. Never negotiate a final price over the phone unless you can walk away instantly — phone negotiations tend to favour sellers.
What if there are competing buyers?▾
If there are genuinely competing buyers, your leverage shrinks. Decide whether the car is worth your walk-away price regardless of competition — if it is, offer it and accept the outcome. If the seller is manufacturing urgency (“I have two other people coming tomorrow”), that's a common tactic. Stay calm, stick to your number, and be willing to lose the car. There are always other cars.
