Used CLK, is it good?

[erin027]

Hi CLK owner~~~
I am thinking about getting used CLK 2001 or 2002. The budget is around $18,000 - $20,000. I never got used car before so I am little cautious about it, I mean who wouldn't, right? ^^

I never owned Mercedes before. Is it good idea to get used CLK?
Also is it better to get it from the actual Mercede's dealer? They called it pre-certified.

Give me some tips CLK owner !!
Thanks!!!

PS. What is MPG for 320, 430 and CLK 55?
