Apologies if this is a bit long winded, but I really want to buy an slk230 (R170), mainly for summer use only. The problem is the rust issue. Therefore, I am hoping you can give me some advice.The main questions would be, are they all prone to it, no matter what age? Is there a date when you can say that they should be ok? (2002 on?), or is it just pot luck? Also, if I find one with no rust, will it rust in the future anyway, or should I just buy a (gulp) bmw? Thanks, Stu.
