I bought 15 of these to make 3 auto body carts in addition to the one I built previously for a Euro Spec Audi RS4 Avant Wagon conversion that we are building. We mostly use them for moving the donor Audi S8 chassis and the Avant Wagon around the shop until were ready to send it out for paint. Also because its a weekend shop project that we need off our lifts M-F. But so far they are holding up really well and there a lot easier to move than the previous metal wheels I used. If your in Houston keep an eye out for a Orange 700+HP station wagon at your local grocery store in 2020.
