I drive a Formentor myself and I'm very satisfied with it. Although it's a relatively heavy car, it feels surprisingly light on its feet and can be steered confidently through corners. At the same time it's also perfectly suited for relaxed drives. But as soon as you start driving a bit more sportily, it responds instantly and shows what it's capable of.

For me, a mature man, the "civilian" version was enough — an automatic, very well-equipped, with the 150‑hp engine in Magnetic Tech.
