Sitting 2 of these units side by side to lift a Smart....Is that gonna leave any room in the middle of the 2 to be able to work under the car? If you have to lay on the unit to get under the car you might as well work from the floor to begin with. Just a thought. DCO
If you are working on the car where the wheels do not need to be removed ; get a set of 4 ramps. Drive the car onto the front set of ramps, then jack each back side up and place a ramp under each rear wheel. You may want to use blocks behind the front wheels while on the ramps to prevent movement.
