Common Problems with 645CI????
looking to buy an 04 or 05 645CI and was wondering if you guys have any tips or advice on what to look out for. any common problems or concerns I should be aware of?
also, what are the optional packages/equipment that are not standard on all 645's that you would consider a 'must have'..
lastly, (no bias lol) but if you had the choice: MB CLS500 or BMW 645?????
