Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Me too, I built mine by staggering 3 2x8's of top of each other, but that just gets it high enough to slide my heavy duty floor jack under the car so I can jack it up to my preferred working height.(YMMV)I have 4 cars I change myself. The lowest is the Miata, which only has about 4" of ground clearance. Even jacking is tedious.
Instead of jacks and stands, I built my own ramps out of wood. They are longer than most ramps, with 3 step ups, and a significant stop at the end. I do chock the wheels.
+1 on lots of cardboard, especially with my stone driveway. I could do it in my garage, but it's much more roomy to do it outside.
