I am considering a 1990 300E in like new condition for $4300 (186K) and a 1986 190E in VGC for $1800 (151K). Does anyone know which one seems to be the most reliable? Both are well maintained cars. The 300E is in like new condition inside and out. I have heard some bad things about the 300E, but not sure. I am also considering some other cars (new and older models) German and Japanese cars, but want to get some input on these cars as well. Thanks!!
