I don't know, I use an Allen Sports bike rack and it works great. I've used it on highways and gravel roads, both were fine. It also doesn't scratch the paint, although the bike itself definately does.
I've been rocking this and it works like a charm. Very secure, no noises or issues. You just have to be a little creative with the trunk being so small and hook the bottom strap to one of the rear tow hooks.
I use this one. I usually always have two bikes on it with no problems. Its cheap, easy to use, and can be switched over to other cars without a hassle.
Thank you so much. Looks like this one will work too

Try this. I bought one but some things came up this year and I haven't been able to use it. :/
