Good question. Since I change my oil every 15 minutes I needed a way to lift the car. I have a 3 ton hydralic floor jack but the C5 sits too low to get it under so I made a couple of ramps out of 2x10's. I cut 3 lengths, 40",27",16" and then screwed them together. I cut the front edges at an angle and added a stop at the top rear. Once the front is up I jack it up further and use jack stands then I jack up the back a little higher to drain the oil. Cost about 10 or 15 bucks for the wood.
