There are a few ways you could do this. You could A. take all of the tires off, B. take only one tire off, or C. if you're really good, leave all the tires on, and find cinder blocks that will barely lift the tires off the ground. If you go with C, the person might not even notice that the car is propped up. This could be potentially dangerous to the vehicle if it falls off, though, so we don't really recommend it.
