Roller jacks.....

Don't try the harbor freight "wheel dollies" where you put them under each tire and can push the car around. They bent on the second use. Couldn't even hold a 72 Challenger. POS! (the dollies, not the Challenger...)

Quality control?

Ive got a the same harbor freight wheel dollies under my 78 dodge power wagon 4x4 W200 project. Been pushing it around for 3 years without issue from the dollies.
