Hi - I am new to the forum. I am about to buy an SL320 W129 (1997). Can't wait. I am looking for a car cover. My main concern is to keep out the moisture/wet as it will be parked on the drive/street. I have had problems with E class of the same period (W124) rusting on the wings/arches after only a few months on the road. I live in Manchester with constant rain that does not help. Any help or advice would be greatly appreciated.
