it wouldnt matter if you had a 5 car garage there is NEVER enough room. me and my dad work out of his 60x40 shop and betwwen his cars and my trucks we always looking to save a little space. one thing we have found to work pretty good is parts such as fenders, doors, hoods etc... that you can hang on the walls will save you a little floor space and you dont run the risk of having more dents from banging stuff in to them to fix.
just be sure they secured good. just a suggestion hope it helps and good luck!
