I am a newish vectra c driver (03 Plate) and the vectra seems to be bumpy when driving. this mainly happens on 30-40 mph roads and not on motorways. When I drive over pot holes and speed bumps its seems to be much worse. Is this normal for vectra 2.2 dti sri ir is there an issue with my car. ? anybody else notice this before or are vectra's generally a bumpy ride. ?

and comments would be helpful.

thanks guys.
