1. Compare like with like
Start with the exact model generation, engine, gearbox and trim where possible. Two cars with the same badge can have meaningfully different values because of specification, age and mileage.
2. Use market evidence carefully
Several comparable adverts help you understand the market range, but asking prices are not guaranteed sale prices. One unusually cheap advert should not become your whole valuation method.
3. Let condition and history move the number
Excellent condition, documented servicing and recent major maintenance can justify paying more than for an average example. Missing history, recurring MOT issues and obvious wear can justify paying less.
4. Add the costs you can already see
Price tyres, brakes, overdue servicing, MOT repairs and other near-term work into your decision. A car that is £500 cheaper can be worse value if it immediately needs £1,000 of predictable work.
5. Build an opening offer and a ceiling
Decide your opening offer, sensible target and maximum before the conversation gets emotional. Good negotiation points are evidence-based: condition, maintenance due, MOT history and comparable value.
6. A valuation is not a guarantee
Market value moves with condition, location, specification and demand. CarSussed shows connected live valuation context when it is returned for the vehicle, then treats its own offer figures as buyer guidance rather than a guaranteed future selling price.
CarSussed approach: use the free MOT result as an entry point, then judge the car using the wider evidence before you commit money.
