Thanks for the reply John...
Guys, I have driven BMW's for years now so i am well aware that they don't feel like the horrible spongy Mercedes. I have mainly driven models with Sports suspension so i am used to a firm ride.
The ride in my GT is not firm, it is just far too crashy going over normal lumps and bumps at no more than 35mph. The last time it was in being checked they gave me a little 118d which was much smoother which cannot be right!
Cheers
Peter
