I have a trunk mounted bike rack. I bought it from Target for 40 bucks I think about a year ago. Works just fine. It looks and seems kind of flimsy but it gets the job done. My bike hasn't fallen off yet.. well I drive slower than usual when I do lug around my bike.

h: I forget the name of the brand. I did scratch my paint on the bumper once because the pedals were moving around. But that was my fault. It came with a tie to hold loose things in place and I forgot to use it. :doh:
