I have metal ones but they slide on the concrete when I try to drive up onto them. I have to put a piece of rubber under them to keep them from sliding. I'm not a fan of the metal ramps. Why not just jack it up and use some good jack stands?
Here's a good looking set of plastic ramps and I think you get the girl in the quasi futuristic outfit if you order today!
