This is not the lift I'm looking to buy but I did spend quite a bit of time in the Shelby display at BJ last week watching these guys swap the suspension out on the Mustang on this setup.
I asked the workers if they preferred this setup vs a two post lift and they both said a two post makes this job easier. That said, they didn't seem to be having any trouble and I could see some advantages to the drive on ramps while doing this job.
The lift was very sturdy, not wiggle at all to it and the car was very secure on the two rolling jacks.
I looked at several of the rolling (or sliding) jack setups and they are pretty slick. They drop down to a 3" height and squeeze in pretty far making getting even a lowered car up on a lift no big deal. The company I'm looking at has wheels on their jacks which roll up along channels on the inside of the ramps which are very nice.
I also found some lengths of rope LED lights with a magnet every foot or so, VERY cool for lighting up under a car on a lift. The magnets let you point the light where it's needed pretty easily.
This is the lift at the top of my list right now.
