I am sure this will have been addressed imany times but a search has not provided the answer. I have a 2006 plus 4. When I purchased the car 18 months ago there was a difference in right hight at the rear. The drivers side being lower than the passenger side. A quick check on the Internet and with Williams confirmed that different heights was not unusual within a couple of centimetres. That said mine appears to be getting worse. As this appears to be fairly common is there. "Quick Fix" or is it a change of rear leaf springs? Any advice appreciated or a pointer to a relevant previous thread. Thanks
