I had it for 11 years and it still mint imperial red because it been in the garage all the time until I bought the SLK 4 years ago. It was booted out in the open for four years, green mosses start to form in the rubber felt around the windows, the recesses of the bumper and the recesses of the front signal indicators. Rusts are starting to form around the rear wheel arches because I neglected to wash off the salts in spring. It still a marvelous car and the ride is better and less stiff than when it was new. Other than the faulty Scorpion alarm I would like to keep it for another 50K miles. It done only 100K miles. At 60K miles the exhaust was free of rust until the snow bound road in 2003 on A14 when the Highway Agency didn't salt the road at Huntington, I was stranded all night and have to drive thru a foot of snow on the road back to Ipswich. Can imagine how the rust got in the exhaust. I like to keep it longer but doubt I can keep it for more than a year after the MOT.
