Thing thing you need to realize about a forum, or the internet in general is that is where people go to complain. Someone has a problem and they want to find a solution so you end up with a huge database of problems listed about a particular car, with nothing good to say because people are not going to post things like "My roof opens swimmingly"
But you can rest assured they will post "My roof won't close" So you need to take that into consideration. Also even if it looks like allot of people on a forum are having a particular problem, their still generally the monitory in overall sales.
That said I have no complaints about mine. I had my roof open almost every day since I got it up until lately when it got to cold even for me. I've have no problems other then my windows freezing, hopefully resolved.
I only have ~3,000 miles on mine so far though
