97 SL320, 150K is not unreasonable. My car is 18 years old and had only 46K when I bought it last year. You don't tell us where you live but "salvage" title cars here in Kalifornia are sort of impossible to get rid of. There is a salvage yard in the San Fernando Valley that is highly regarded. They also rebuild Benz transmissions. And MAVA on the other forum is an expert on salvage yards.
