Man, that kwiklift is cool. What'd it cost?
I'm going to an auction Thursday where a two pole vehicle lift is on the slate.
Back to topic, I greatly prefer jackstands. It takes more time to jack the car up, but the stands are a lot more rugged, and you can place a second set of stands as backup to the first set. I take no chances when I am under a car.
Besides, anything involving removal of a wheel is impossible with ramps.
Unfortunately, my last two new car purchases, a 2004 GTO, and a 2004 Jaguar Xj8, are not very jack friendly, so I bought a set of the Rhino ramps for these cars. They are adequate for changing oil, but that's about it, and I don't feel safe under the car.
