So, I just had my polycarbonate roof replaced a week ago (it was spider-webbing), only to have a catastrophic failure 2 days ago...
I work at 4am, which was a God-send Thursday morning! It's a little hard to hear small noises in my smart due to the Breathless exhaust, but I could definitely hear the roof rattling as soon as I got onto the freeway. The more I got up to speed the louder the rattle became. As soon as I hit about 65 mph the roof took off; seemingly on a mission from NASA. By the time I could get turned around to try to retrieve it, it had been obliterated by a semi. When I got the car home I could see what the reason for failure was. The dealer forgot to peel off the plastic tabs so that the double-sided sticky tabs could hold the roof down. The only thing securing the roof was the weather sealant.
I'm just thankful that no one was driving directly behind me. To me, the worst part about it was when I returned to the dealer. They refused to give me a loaner car, citing all sorts of "legalities" with the Mercedes loaner program. Finally, after 4 hours of waiting, they let me take the smart demo car. They made me to feel like I was pulling their teeth to get it, but the whole scenario was their fault and their problem! I have half a mind to see if their is any ground for suit...
Anyway, that's my drama for the week. My smart has been the source of quite a few headaches in the last year. I don't think I could convincingly recommend a smart to anyone at this point in my experience. I hope no one else has had the service frustrations that I've had...
