I own a Back Yard Buddy which I use to stack my cars on and also we use it to work on the vehicles, change rears, oil, I bought mine and had a garage door company come out and move my Tracks of my garge door to the ceiling and put a side mount opener on the door. It has worked great we now have turned a three car garage into a four car garage.
I also had a couple of buddies over to put it together it took about 3 to 4 hours. If you do a search on the net you can find all kind of companies, I am real pleased with the level of support that Back Yard Buddy gave me while I was installing the unit. I think I paid around 3200. with shipping. Good Lucj\k If you need picture let me know and I will post.
