My 560SL has 154K (bought 12/02 at 145K) and feels strong, solid and quiet; I really don't find mileage an issue, excepting only that it tells you what maintenance should have been done. (Key example: Knowing what I know now, I would have asked if timing chain work had been done. It hadn't, and I got to it in the nick of time--one upper rail was broken but hadn't trashed anything yet!)
I bought the car for driving, and would have more anxieties about a low-mileage car as far as what's getting old, deteriorating or degrading; when the car's used regularly, you know when something starts needing attention.
