Ok, I never own a Mercedes but thinking to get a v6 CLK. I am shopping for a Z3 2.8L but found couple high mileage (around 100K) CLK on autotrader too. Here are my questions:

1) Is CLK reliable?
2) Any maintenance need to be done around 100K?
3) When should I replace the timing belt/water bump or similar major mainteance?
4) Is $15K too low for a 98/99 ~100K CLK?

I live in Arizona and don't mind drive to LA to get one if it worths the money.
