Make condition easy to understand

A clean interior, clear glass and consistent exterior finish help buyers assess a vehicle. Preparation also reveals damage that should be disclosed rather than hidden.

The sensible scope follows the vehicle's likely value and condition. Cleaning may be enough; polishing is worthwhile only where correctable defects affect presentation and the paint supports the work.

Do not promise the sale price

No detailer can guarantee that spending a certain amount will produce that cost plus several hundred francs at sale. Market, history, mileage, maintenance and demand remain decisive.

The original CarSpa article promised risk-free profit and last-minute mobile preparation. Those claims are historical. AVP now recommends completing the work early enough to inspect, photograph and present the vehicle properly.
