Those lifts are great when working on wheels/brakes/rotors , cleaning car , exterior work like mounting bumpers.Great when your back is killing you when you have to bent your spine to get some work done beneath or in the wheelwell.
Not useble for motor/tranny/driveline/exhaust/bottom sheetmetal repair.
I have a 4 post lift with a pit underneath of 3 feet and is very workable.
Total height is about 2,60 meter or 9 ft i think.
