Just bought a 1986 300E and the car feels like it floating all over the place when driving down the road, what is the deal? I dont think it is the shocks. The blower really doesnt blow that much even when it is on high, what should I look at? The back windows do not work, Fuse? I also have some rust on the jack holes, is there something I can do to fix that? Thankyou for all of your help.
