Can a garage be too big?

When we were looking for our current home, my wife went and looked at one while I was at work. It had a 2 car attached and a 60 X 100 garage w/2 stories. She said it was way too big. We didn't get it, but this house is much nicer than that one. This one has a 3 car attached and a 1 car detached which is 13 X 30. I figure I can always build an additional building later, if I need it. 60 X 100 sure would have been nice though, so I guess the answer for me would be no.
