We read everything. If you have spotted an incorrect figure, a missing car, or something that does not work as expected, tell us the page and the details and we will investigate.

Report a data error

Accuracy is the reason this site exists, so data corrections are the most valuable message you can send us. Please include: the calculator and market (for example "Germany — car cost calculator"), the figure you believe is wrong, what you believe the correct figure is, and a link to your source (an official body, regulator or manufacturer page is ideal).

If your correction checks out against an official source, we update the default and credit the source in our data documentation.

Request a market or calculator

We are actively expanding. If your country is not covered yet, tell us which country and which costs matter most to you (fuel, road tax, insurance, inspection fees). If you can point us at the official data source for your country, all the better — that is usually the only thing standing between a market and launch.

Response times

This is a small independent project, so we aim to reply within a few working days. Data corrections that come with an official source are prioritised.

Advertising and partnerships

For advertising, data licensing or partnership enquiries, use the same email address and put the topic in the subject line. Advertising never changes our figures or editorial decisions.
