Just got the latest email advert from Eastwood. In it they show the latest device to help you work on your car. At $1400 it is a little pricey for something that doesn't look too complicated. It says that you can use an electric drill to crank the car up, so I am assuming that there is a geared jack screw that does the work of tilting a vehicle of ≤ 6800 lb up to a 90° angle.
