Re: side mount or continental
Any donut spare that is for the SLK 320 will fit our wheel. I got mine off e-bay from a salvage shop in Calif. It was off a 2002 SLK320. Was never used came off a total. I put air in, tried it on one front & one rear wheel & was a perfect fit. Measure it's dia. & get yourself a trailer tire cover off e-bay close to the same color of your trunk liner & it sits in their almost unnoticed unless you peer in thru the back window to check.
