I just ordered a set of ramps that look pretty good on advice from a friend from the Corvette forum. They are designed for low sports cars so cars will not drag going up. The Corvette forum had a discount going with the manufacturer for 15 percent off. I found an OK deal $329 which offered free shipping. I also bought a set of their wheel chocks for $20. I like the two piece design so that you can remove the back portion of tha ramp after you go up if you need the access. They also make them in one piece design for less money. These give you a full 10 inches of lift and are nice and wide. I will follow up after I use them. Might be a possible discount item for our Xfire group. This is the vendor I used:
