I have a 92 500 SEL all of those things have gone wrong since the warranty ran out in 96. If you think about it that is in the last ten years. I figure 2K /year and some is maintenance. If you get one with good records you will see what has been done. The most expensive (AC $4K), (Bose $.7K), (Close assist $ .8) motor mounts, suspension parts, brakes, tune ups are maintenance. Find one that has been serviced you will be happy!
