I agree with the clearance issues .. It'll work, but I don't think you'll get your car up as high as you'd like for certain jobs ... The ceiling in our shop is 14' high, and when the lift is fully extended my Duster roof has about 6" of clearance on top ... If I had to drop it down 3.5', which is the room you'll have, I wouldn't be a happy camper ...
Best of luck,
Kenny
