Opel Signum reviews
Total 11 Opel Signum owner reviews
Pros: The running gear is quite wobbly, even on dirt roads. The interior is quite comfortable, i.e. I don't have the full set-up, but there were no problems when driving long distances! The audio system also sounds pretty good, and the engine itself hasn't really been a problem. There is plenty of room in the back and the boot is quite big, I could easily fit 2 (mountain) bikes without any problems.
Cons: The rolling stock might be slightly cheaper in terms of price, but there's nothing to complain about. So far, the car has not disappointed!
