<< The reason I ask is, the dealer here has a '98 SLK 230 with 50,000km (~30,000mi) on it for $35,000CDN (~$22,000USD). I've always wanted a convertible, but I can't get a softtop one because of the weather here. >>
That's actually pretty cheap, if it is in good condition w/ average mileage. It's tough to find a used SLK for under $30K U.S. around here.
