Here's a shot of the "Cobra Wall" in my garage:
Wish I had more wall space, as I have plenty of posters, but tool boxes, cabinets, and storage shelves are more critical in a working garage.
The lift was one of the most useful tools I've bought. What used to take me a couple weeks to detail the underside of the car for a big car show
(car on jackstands, me crawling around under it), now takes just a few hours. It also allows me to cram four cars into a three-car garage.
