The TSYS system in my signature is the most advanced vehicle management system (to the best of my knowledge) that's been released and it does what you want but it's actually part of a much larger system and may actually do far far more than you would want. What you are after is really pretty complicated but is doable. for an example of how to use the tsys system check out the rpg 5.0 link in my sig. It will even save vehicle parking positions over a server reset etc as it loads and saves the vehicle information from/to files.
