Anybody know if these things are any good? I quite like the look of them, but I don't think I've ever really seen anybody talk about them online. Are they reliable enough to DD? Exceptionally expensive to maintain? I won't be buying a new car for a few more years, but I'm doing some preliminary research on 80s/90s convertibles (my target category) and I'm having a hard time finding much about these. Should I even consider it or is this just an older person's weekend toy?

Edit: I know an old MB is going to cost more to maintain than a Civic/Miata/whatever. I just want to know if it's bad compared to comparable cars.
