I went with 50 foot wide, as it allows for 5 cars width wise. It is nominally 24 ft deep, on the ends, with the center bumping out to 30 ft deep (you just don't see it unless you walk around to the back). 16 ft truss ceiling (car lifts can go in any bay). I have 9 cars in it now. 9/12 pitch roof works out well too.

I chose to build a second car storage/paint/ body work garage (20x25) down the road (much cheaper floating slab foundation), versus adding that to the main garage (that has a heavy duty expensive foundation). I have a 1800 square foot limit for 2 out buildings. So I went with a 1300 square foot and a 500 plan.
