Yep, I did and I love it.
I mounted the pump on my wall. For projects like replacing the fuel lines in the tunnel I just sat on the edge of the pit, and straddled the lift arms. Changing transmission fluid is still very easy.
I love my scissor lift. I will put my car up in the air to wax it, or do electrical work, or just about any excuse.
When the lift is lowered, the 1/2 inch piece of plywood covers the hole and it is pretty much gone. The plywood is great for lifting weird items like my lawnmower or BBQ grill to work on them at a comfortable height. We even painted our front door on it. Sure beats bending over.
