At 100,000 miles the interior will have fallen apart and the tranny will be shaky, if not replaced yet, and you will be facing running gear problems and parts availablity problems.

GM cars are fine it you only keep them a couple years, will drive you nuts if you expect it to run any decent amount of time -- the heater blower in the new Chevy Coronado truck I rented a couple weeks ago was squealing at 40,000 miles. I expect things like that in my 300D at 200,000, but not nearly new!

You'll be back in a Benz sooner or later....
