Rear ended 66 cuda advice

I had a GMC Typhoon stolen.
I made it very clear up front this was not a Jimmy or Blazer, as the insurance company started the conversation with.
I used Ebay and Autotrader.com to bring them examples of similiar condition vehicles, and used specialty sites, to document the specialty nature and rarity of the vehicle.

Be nice until it is time to not be nice. Human nature says that you take care of the easiest projects first, so you need to present your case well, be nice, so that you make your case as easy as possible for them to deal with. (Who would you prefer to deal with, nice guy or raging #$$hole?) Document, make your case, and you should come out ahead of the game.
