To relocate a car, press Shift+C to go into free cam and hit F7 to teleport the car to the camera's location.
Press Shift+C to go into freecamera mode, move the camera with WASD to a clear area without anything to get stuck on. Then press F7. If you are satisfied with the positioning, press Ctrl+R to fix any damage done to the vehicle from dropping it or spawning it underground. Enjoy!
