I just picked up a nice old heavy duty set of ramps for $40. There are a couple of options. The ramps can be removed once the car is up, so crawling under the sides is easier, and the removable plates allow the front wheels to be turned. I was window shopping through the FB Marketplace when I saw them. They had only been posted a few hours earlier. The seller wrote that I was first, but should get there early this morning, as he had received a lot of interest. Sure enough, he scrolled down 5 pages worth of inquiries on his iPhone to show me this morning. I'll just have to remember to reinstall the ramps before backing the car down off them.
