I just got a new car and the main requirement was that I can put my bike inside. I don't like hitch or roof racks because they all can cause problems with the bike (well, my forgetting they were up there and running into an overhang, or someone rear-ending me with the bike back there.)

So, I put mine inside my SUV. I got a truck bike rack: http://www.performancebike.com/shop/...tegory_ID=4413 that expands to lock into the sidewalls of the SUV.

In my old car (Acura Integra hatchback), I would put down the back seats of my car and put down a blanket. I would remove the front wheel and just lift the bike into the back of the car. It would take less time than a bike rack since I just lay it down and go.
