On any used-car listing, Car Deal Checker shows whether the price is good — backed by real, comparable cars listed right now, not a black-box estimate. Works on coches.net and mobile.de.
Go to a car on coches.net (Spain) or mobile.de (Germany). The deal panel appears on the page.
One check spends one credit — and the cost is shown on the button before you click.
See the verdict, the real comparable cars (each clickable), how far the price is from the market median, and a labeled estimate.
Every other tool gives you one guessed number from a model. Car Deal Checker shows you the actual market: the real cars a buyer would compare this one against, live prices and all — so the verdict is something you can click through and check yourself. The model estimate is still there, clearly labeled and kept separate, never dressed up as the market.
1 check = 1 deal verdict. Credits never expire. No subscription.
