I currently have a BMW 325i and I ran accross an ad of a 1990 MB 300SL. Anyone know anything about this car? The ad didn't say anything about convertible. I thought this year model always has convertible. Am I right? I also like to know about reliability, service maintenance cost of this year model. I plan to come and check it out tomorrow morning. Anything (part, feature, etc) I should pay attention? Please input anything you know about this car. Anything is appreciate.<br>Thanks.<br>
