Another bike rack question

I keep changing my mind on what I want to do. First it was roof rack, then hitch mount. Now it's trunk mounted.

Has anyone had any luck with a trunk mounted bike rack? I think the spoiler would get in the way of most racks.

 

I know the Saris Bones ones won't work. I'm so happy I went hitch-mount. Nice and easy.

 

I use a trunk rack, but instead of using the top straps that come with it I run a strap from either side up around the spoiler to the roof rack. I'd rather have a hitch mount one, but don't have a hitch yet :/
