Comparis evaluation

1. How we evaluate

The Comparis evaluation assesses the price of the car in the ad and helps to better estimate the attractiveness of the offer.

Market price and savings potential calculates the market price for the ads. It complies with the average price of comparable vehicles offered on the Internet. The prices calculated by are market prices that can vary from the selling price depending on the condition and optional equipment of the vehicle. The savings potential indicates how much lower the selling price of the advertised car is compared to its market price.

Comparis Rating
The Comparis Rating rates the competitiveness of the selling price compared to the market price according to the Swiss school grading system. If the selling price corresponds to the market price, the advert is given the average grade 4.5 (satisfactory). The cheaper an offer, the better the Comparis Rating.

Mark 6.0 - 5.5:   very good (the advertised vehicle is very cheap in comparison)
Mark 5.4 - 5.0:   good (the advertised vehicle is rather cheap in comparison)
Mark 4.9 - 4.5:   satisfactory (the price asked for the advertised vehicle is average)
Mark 4.4 - 4.0:   adequate (the advertised vehicle is rather expensive in comparison)
Mark 3.9 - 1.0:   poor (the advertised vehicle is very expensive in comparison)

2. Method

The price evaluation of the vehicles for sale is based on a statistical model by ETH scientist Andreas Keller. is continuously collecting comprehensive data on the vehicles offered online. Based on these data, the devaluation of an advertised car over time is calculated individually.

3. Exceptions

New cars are not evaluated by; neither are vehicles of which has only very little market information (rare or very expensive vehicles such as classic cars). Please note that cannot take a vehicle's special features such as custom builds and tuning parts into consideration for the evaluation.

Accident vehicles
From the data available, is not always able to detect if the vehicle for sale is an accident car or not. The price calculated by is always based on the assumption that it is not an accident vehicle. However, if a vehicle is marked as an accident vehicle in a clearly evident way, it will be excluded from the evaluation.

The vehicle valuation is based on the assumption that the vehicle condition complies with its age and the driven kilometres. Mechanical defects, defects of the bodywork and interior equipment, bad tyres or other defects – also due to accidents – cannot be taken into account.

Optional equipment
The market prices calculated by apply to vehicles with average equipment. Therefore, selling prices for particularly well or poorly equipped cars can vary strongly from their calculated market price.
