Why was http://www.imcdb.org/vehicle.php?id=586198 (a Nissan or Datsun pickup truck in the background of a closeup of Bernard Stevens on his motorcycle in Northern Exposure episode 1-8) deleted?

Also, the site needs an option to show added vehicles (not just comments and pictures--which doesn't actually show one's pictures but just annoyingly links to the series) in one's profile and get email notification if a submission is approved/denied (and why).
