I am very interested in a 2000 c70 convertable and was wondering if anyone had any information that would help me decide this is a smart move. I have found one with about 33,000 miles, it looks like it is great shape, except there is a water mark on the inside of the top, rear passenger side. I'm trying to figure out the best way to figure out if there is a problem with the top or if someone just opened the top on a wet day and while it was folding down or back up the inside got wet. Has anyone heard of any top leakage problems? Or for that matter any other problems with this car. I think the one I found is a LT model. Is there an easy way to tell the difference?<p>Would you think it's a good idea to pay Volvo $100.00 to look over the car before it was purchased, or any other mechanic? Or if it passes a state inspection would that be good enough.<p>I've never purchased a used car before so I just want to make sure that if I purchase this I do it right.<p>Sorry for all the questions but any help would be greatly appreciated!
