Mechanically the car is fairly well built, apart from the rear axle.
The air conditioning is effective and visibility is good, while the FR setup paired with the 18" wheels, in my view, hurts comfort — getting in and out can be awkward. Once on board, though, the seats are very comfortable. The infotainment is comprehensive, with a generously sized screen and full-link smartphone connectivity; the factory sat-nav does what it can, but obviously Maps is superior in every way.
All in all, a fun/sporty car that also winks at family life thanks to a roomy boot and modest fuel consumption.
