It is possible.. Just /save in SA:MP when you are inside the tuning garage, look in savedpositions.txt, take the XYZ coordinates and use SetVehiclePos on a command, checkpoint or wherever you want it.

Oh, it's an interior i guess, so do /interior in SA:MP, it tells you the interior. and SetPlayerInterior, LinkVehicleToInterior in the script.
