I'm like you, Bob, the two posters seem scarey and tipsy. We are getting close to buying one ourselves and I asked this question on another forum. It seems no lift is perfect, some have good access underneath but need a certain frame setup to work, and others are solid and will pick up any kind of car, but the ramps get in the way sometimes.
When I get one I want it to be totally safe because my two Sons will be under there, and there have been some documented cases of cars falling off of lifts or the lifts collapsing.
