Alex,
A question. I looked at the brochures on that type you have and couldn't find out a couple of things. One is how strong are the center legs that take all the weight and movement ? Two, can you adjust the width and length ? I went with the kwick Lift because I just didn't know back then about what this type was like. I really like my kwick lift as I can adjust it for my other cars very easily. The jacking is the only work to it, but I have wondered about your type. If it is adjustable and will stand up to heavy cars then it would be a little less work. As for parking brakes, mine holds just fine with the ramp down and the engine running. I just have to be careful that the darn thing doesn't shake itself off the ramp as mine has quite a lopy idle.
Thanks Ron
