Shop layout recommendations?

Just for information, I have a 2010 challenger with an 8 Foot garage door and have about 2" on each side when entering. When I pull my 05 Ram in both mirrors are in. I added a 3rd car garage and when I did I never realized how wide cars were getting. After cement was poured, He said could have gone with a 10 foot door. So maybe a double door might be a good idea.
