To clarify a couple of points:
A) Most lifts (or components thereof) are made in China - mine included.
There is one I looked at manufactured totally in the US, but it was increadibly over-designed with a price tag to match ($30,000.00).
There is not much point in having a 10,000 lb capacity lift for a 4,000 lb car.
B) The issue with the concrete thicness on the floor is not horrible to overcome.
A section of the existing slab (about 3 ft x 6 ft) needs to come out, dig down and remove 6" of underlying base, then cast a new reinforced concrete 'panel'.
Have somebody knowledgeable take a look at the base, and the reinforcing, before placing the new concrete.
C) The introduction of 4 legged bar stools into the
"help, I've fallen and can't get up" analysis will surely taint the results offered.
Singnificant research and data collection remains outstanding.
