I've been thinking about this for awhile and now that my 2 car garage is drywalled I think I'd like to put in a lift that allows me to park on it or do some work on the underside of the car or park underneath. To the ceiling I have 10ft 10" of height which I think is not a problem.
I know I have to raise the door track height and go to different style of garage door opener.

What other things should I be thinking about?
Any recommendations on a manufacturer, or style of lift?

I would want to purchase from one who delivers and installs.

And lastly any estimates on much I should budget to do this?
