What does a car rotisserie do?

It holds a stripped body shell at each end and lets you rotate it, so you can weld, sand and paint the floor, sills and underside while standing upright instead of lying under the car.

Is 4,500 lb enough for my car?

That rating covers most full-size car bodies and many truck cabs once the frame, engine, interior and glass are removed. Weigh the bare shell before you buy if it is a large or heavily modified vehicle.

Can one person turn the car on it?

A bare shell balanced on the pivots can usually be turned by one person, but a heavy or unevenly loaded body may need two. Lock the rotation before you work under it.

Does it need to be bolted to the floor?

Most rotisseries of this type stand on their own base and do not need floor anchors, but a tall, heavy shell raises the center of gravity, so keep the unit on level, solid ground.

What do I need to mount a body on it?

You need a hoist or several people to lift the shell, plus the mounting arms or brackets that attach to the body's bumper or frame mounts. Check that the arms reach your car's mounting points.
