I park my Viper on one every day. It is great and does not take up too much room. Powder coating and all the accessories I think I was in around $1300.00 delivered to a local warehouse. I bought two of the jack braces that go across the ramps, the only problem is it is hard to find jacking points as most of the frame is covered by the ramps. So brake work etc may still have to be done on your garage floor with jack stands. When doing a clutch or headers, exhaust, etc it is great. For the clutch you can sit up straight in the tranny tunnel, once the transmission is out, and bolt the clutch up, actually easier than a stand underlift in that respect. I did headers on an F-body, it got the car up high enough to send the headers in from the bottom, big issue on long tube install on an f-body. I did a Corsa install on an RT-10, the ramps made the job a lot easier. The Viper rear tires will just fit on the ramps, but you have to make sure you are dead center or they will over hang. Also, if you pull on it and the tires are wet be very careful with the throttle and clutch engagement. The ramps are very slick when wet, I almost learned the hard way one night. Great product and well built. Mine is bright yellow, grease and dirt cleans off very easily.
