The Seat Ateca is a very affordable SUV with excellent handling and plenty of space for the whole family. A companion that can do it all and is equally suited to everyday use as to long trips fully loaded. A very good choice for the active family that needs a car that fits most needs.

+ Great, firm seats, large boot for such a compact car, good fuel economy, lots of interior space, uncomplicated controls, very agile and safe handling, good build quality, very good steering, good braking performance, relatively small turning circle
- Very poor voice control and navigation, cockpit display too small with very small fonts and symbols, steering wheel too thin, seats too flat despite electric adjustment, poor engine soundproofing, tank far too small, complicated maintenance (oil change appalling), undersized rear brake, fuel filler on the wrong side, sound almost without bass (Beats)
