I know that autoshops have the pits beneath cars, but is there something that can lift the car up into the air and allow you to stand beneath it?
You can buy a hydraulic lift for your garage but keep in mind they are expensive and you need the proper overhead clearance.
the lifts you are thinking about starts around 4000 not to mention the tall shed you would heve to have. i had to settle for car ramps start bout 20 buck :0)
