Well, I like (relatively) cheap cars and I would have a lot of money, so I'd build the second garage we're talking about and put a 356, my Beetle and something else in there. "Something else" refers to a 2002, 240Z, Chevy II or??? Perhaps the wife's hot rod will go in there.
Oh, and the garage would be big enough that I'd have a clean room for building engines. And a couch/flat screen/fridge/half bath.
