The only thing I can say is make sure your door(s) is big enough to get any possible vehicle into the garage.
We built our house 18 years ago. While the garage is ok for cars, in hind sight, I wish the doors were larger than the standard 16x7 & 9x7. The last time I tried to get the truck inside, it was within an inch of hitting the top of the door opening.
I also wish the garage were a few feet bigger. A long bed super cab doesn't leave a lot of room to get around it with the door closed.
But then again, I suppose a 40x60 shop would have a door big enough for a semi-truck.
