The top failed, only 1000 miles so far. The top has been operating intermittently for the last two weeks. It stops part way either up or down and about 15 minutes later the roof failure error will clear and it will finish the cycle. Yesterday I took it into the shop with a hard roof failure that wouldn't clear overnight, I tested it before I took it in. As soon as the tech sat in it and started it up, the roof failure had cleared and he could get it to go up and down. They kept it, will look for codes. In the meantime, I don't have my Ferrari and am stuck with the RR, sure wish I had been able to keep the 991tts.
