Saw a really neat - and relativey low cost - car lift. It is a ramp built
of welded angle iron - maybe aluminum -  so that as you drive up the ramp
to the center point  and slightly beyond, the vehicle goes over center,
tilting to level and making the vehicle level, then the vehicle is moved
slightly forward to stabilize the whole thing for maintenance.

This would be handy and inexpensive for some home shops.
