I bought a 1991 190e 2.6 with 75k miles on it from my best friend ( a former Huey Cobra pilot in the Nam). He maintained it religiously. I booked another 70k on it before my daughter totaled it by t-boning another car. At the end of it's life it was still going strong and I had planned on keeping it another 3 or 4 years. The cruise control gave up at about 120k and I never fixed it. The auxiliary cooling fans seemed to run a lot...maybe a sign of a failing water pump.
Apart from that, my only major gripe was in climbing in and out of it. I'm a 6 footer and had to drop in seat first and swing in...couldn't really step into in with right leg first.
FYI, the insurance settlement was $7,700 in Nov 2001....a fair price I guess....
