My girlfriend has a 2002 CLK and its a pretty awesome car I really like it. She's put about 3k on it since February when we bought it for $6500 @ 104k on the clock and not a single issue since purchase.

You are definitely going to pay the premium for a 2003.

Whatever you do, transmission service history is important, or bank on doing it immediately.
