We have a Roush Racing jack.....funny because we own no American cars and never owned a Ford
Something like this
It works great, good for 7000lbs. It is extremely heavy though, I brought it over to a friends to do pads and rotors on his GLI this weekend, and when I put it in the trunk of my Jetta, the car seriously came down 2 inches....haha
We need an extra one though, one that is low profile as both my car and the M6 dont go under the Roush, unless you lift up on the car a bit. Most likely a Craftsman
