In the historical comparison, the prepared vehicle sold for CHF 19,500 and the untreated vehicle for CHF 17,000. AVP had invested approximately CHF 500 in preparation at the prices then in use.

The result shows that presentation can matter, but it is not proof that detailing always adds CHF 2,500 or produces a fixed return.

Two vehicles can differ in options, history, tyres, mechanical condition, buyer interest and negotiation even when model and mileage are similar.

Before sale, AVP can assess whether cleaning, local correction or a complete preparation is proportionate. The aim is to present the real vehicle clearly, not promise a particular selling price.
