With only a Vette & a Jeep, obviously he's a piker. But here's where he really screwed up...............
First, he should have 10' wide doors spaced about 4' apart. This will give enough room to open doors fully and still be able to comfortably walk around them.
Second, he should have had at least a 12'-0" ceiling in there to be able to have a lift or two.
Third, brass door hardware is outdated. Brushed nickel is the finish for today.
Fourth, he should have had a couple dormer windows overlooking the driveway so he can see who's pulling up.
Other than that, it looks ok.
