Prep Costs Most Car Traders Forget Before Pricing Stock
Profit often leaks through small prep items. None of them look dangerous alone, but together they can turn a good purchase into dead money. The fix is to track prep as a cost stack from day one.
Tyres, brakes and suspension advisories
MOT advisories are margin warnings. A car with tyres close to the legal limit, brake wear, suspension knocks or corrosion notes may still sell, but it can reduce buyer confidence or force discounting.
Use MOT history to spot repeated advisories and mileage patterns before you price.
Diagnostics and warning lights
A dashboard light can mean a cheap sensor or a costly fault. Even when the repair is simple, diagnostics time, parts delay and retesting should be included.
If you cannot price the fault confidently, carry a risk buffer or walk away.
Valet, paint and presentation
A retail buyer judges presentation quickly. Valet, odour removal, wheel refurb, dent repair, bumper marks, headlight polish and missing trims all affect saleability.
These are not vanity costs. They influence photos, advert response and negotiation pressure.
Keys, documents and admin
Second keys, V5 timing, book packs, invoices, plates, mats and small admin items are easy to forget. Some are small costs, but they also affect buyer trust.
Build a handover checklist so the final sale does not become messy after payment.
