Looking for a used car should be as simple as getting an email.
Every morning a system goes through the used-car sites, keeps what's new and fits what you're looking for, and emails it to you, sorted and explained, with what similar cars go for so you know whether the price is right. In Spain and, if you'd bring it from abroad, in Germany, Italy, France, the Netherlands, Belgium and Austria. No accounts, no app. Just email.

Which car (make and model, one or several), your budget, how old and how many kilometres at most, petrol, diesel, hybrid or electric, manual or automatic, where you live and what it must have: rear camera, tow bar, seven seats… And the rest in your own words: big boot, one owner, full service history.
What you get
One email a day with the new cars that fit best, and a weekly summary on Sunday. Each with its price, year, mileage, fuel, gearbox, power, where it is and why it's at the top: below what similar cars go for (same model, close years and mileage), low mileage for its age, near you, with warranty, one owner, or the price has dropped. And what doesn't add up, flagged: dearer than similar cars, too cheap to be true, or abroad and you'd have to bring it over.
The same car listed on several sites arrives once, damaged or "for parts" cars don't arrive at all, and what you've seen isn't repeated unless its price drops.
