I purchased a 1991 Q45 and I have two questions maybe someone can help me with. 1. The car makes a rough sound jittering rough when it accelerates to 40mph but then it sounds okay? any suggestions. I wish I could be more specific, but it only happens upon acceleration the interior is horrible. 2. Can i swap out the 1991Q45 interior with the 1993 Q45 interior?
Thanks for your help. New and Enthusiastic novice!
