Is the Saturn dealer already "appraising" it or did you stop that? Can't hurt to wait until they come back with their estimate - you might not need to take it anywhere else.
Raintree, Fat Albert's, Stuttgart SW - call high end dealership (BMW, Lexus, MB, Porsche) and see who's doing their body work. Look for European paint (Spies Hecker, BASF/Diamont/Glasurit, anything else "Euro sounding") or PPG. Not a huge fan of Dupont or Sherwin Williams.
Oh and make sure they know you want NEW OEM panels (not used or aftermarket) for the estimate.
Good luck on getting it totalled! Had a friend with Allstate get his car totalled - the adjuster said it's usually around 83% of the value or more will get it totalled.
