Timing the sale of a performance car (UK guide)
When to sell, and why before-market offers beat waiting for the open market. The depreciation triggers, mileage thresholds and seasonal patterns that decide how much value you keep.
The best time to sell a performance car is before a major depreciation trigger — a new model or facelift, a round-number mileage threshold, or warranty/MOT expiry — and selling before-market to specialists protects value better than a slow open-market listing.
- 15–35%
- Typical value lost in a car's first year
- ≈50–60%
- Common value lost by 3 years / 36,000 miles
- 60k / 100k
- Mileage thresholds that visibly step value down
Watch the depreciation triggers
Value steps down at predictable moments. New cars commonly lose roughly 15–35% in the first year and around 50–60% over three years and 36,000 miles, but performance cars move in steps rather than a smooth line: the launch or facelift of a successor model, crossing a round-number mileage (30k, 60k, 100k), the end of the manufacturer warranty, and the approach of a major service interval all trigger a drop.
Selling just ahead of these triggers captures more of the car's remaining value. Crossing 60,000 or 100,000 miles, for instance, can move a car into a lower buyer bracket overnight even though nothing mechanical has changed.
Season and UK market demand
Seasonality is real in the UK. Convertibles and summer sports cars are strongest from early spring into summer, while robust performance saloons and SUVs hold up year-round. The plate-change months (March and September) flood the market with part-exchanges, which can soften prices around those windows.
Specialist demand, however, is driven more by spec and condition than by the calendar — a rare, well-specified car finds its buyer in any month. Use the seasonal pattern as a tailwind, not a reason to delay a sale on a genuinely desirable car.
Why before-market timing wins
The danger of 'waiting for the right moment' on the open market is that you often cross a depreciation trigger while the car sits unsold. Before-market offers let you test real demand without committing to a public listing, so you can move quickly the moment the timing is right.
You build a Spec Profile once and review competing specialist offers in one place — which means you can act before a model refresh, a mileage threshold or warranty expiry erodes your number.
