I use my 1990 500SL for daily use/abuse and it has never missed a trick. Here in Arizona we have 330 days of sunshine a year and this is definitely the car to own. I currently have 142,000 miles on the odo. The car was recently driven by a regional MB zone rep and he commented how well it has held up, of course with normal maintenance and repairs when necessary. On the whole it is quite trouble-free.
