Congratulations - sounds like a deal to me! Welcome to the club - you will enjoy it. You can stop the roof at any point and restart if you want to do a little cleaning etc but if you leave it part way up or down for too long I think it drops by itself. You may have to do a search to see how to correct it once it drops - I know someone wrote about it before. The search will get you almost any info you can think of as almost everything has been done by someone on the forum! Have Fun.
