I'd make some low-profile ramps leading onto a flat "track" out of 2x or plywood.
Make the front and rear part of the track fixed to the ground with something light-duty like water-based caulk.
Make the cetner section of the "track" removable.
Idea is its all assembled into one ramped, track. The car sits either 1.5" or 3" higher than normal.
When you want to use the lift, simply pull out the center section where the wheels are not resting. Now you can swing the lift arms in, and raise the car up normally.
Set the car back down, now reinstall the center portion of the track, drive car back out for road testing.
It might be better to have the entire track and ramp asm removable, but if the ramp angle isnt shallow enough, it can start to "push" rather than the wheel climbing it.
