Short answer is-----it all depends on how big your cars are and how extended your garage happens to be. A tape measure will give you the answer in your case. Obviously, the most convenient would be a two car garage with a golf cart garage----it will also be the most expensive as you will need a lot larger than the standard village lot. Regardless, I would highly recommend extending the garage depth by 2 feet---you will be glad you did!
I'm amazed all the time at all of the things people can fit in their garages
