Hi, I've had great luck with this site - put my 740 in garage for a year, running great, the sunroof was cranking after alot of babying, now is stuck shut, will vent but nothing else, the a/c was disconnected yrs ago, so sunroof is a must. It was not closing evenly, I would push on it from ourside, now the crank will not even turn - a man was helping me shut it in the rain. Some water marks on the headliner, but they've been there for years.
