Newbie first Merc purchase.
 

Hi all, looking to purchase my first Merc and have tentatively decided on a 2000-ish CLK 320.(3.2L V6) Prices have become quite reasonable and they look to be a quick, sporty, practical, well built and FUN coupe. If I do go with one, it will be my daily drive. Just wondering if there are any common faults I should look out for.
I also hear people say the service costs are outrageous. These People have never owned one, nor can they tell me the costs of scheduled servicing. Any idea where I can find info on parts/servicing costs?
Or should I look elsewhere in the Mercedes stable at a different model?
Any info is much appreciated. (I'm in Australia though that shouldn't make much difference).

cheers:D
