I would try and list your car on Ebay or Craigslist first to get a feel for the market. Pontiac collectors are finicky. Most go for the Ram air HO and Super Duty stuff. A very small limited number of guys go for what you have. You'd have to find a buyer wanting that color, year, condition...you can find 30 buyers at 20k, 10 buyers at 30k and maybe 1 or 2 at 40k. The key is to get the word out with Mecum or Barrett Jackson. Keep in mind you'd want to watch the lots up for auction and consider pulling out if comparable birds in your condition dilute the auction. No seller wants to go to sell a firebird on a buyers market where there are 8 birds up for sale. As far as consignment..you are at a tough spot to sell geographically. Even for Mecum or BJ, your transport costs could be 3k plus...so, that's also a consideration.

Taking this into account...you may want to split the difference with incurred expense (transport costs to auction, sellers fees, premium) and perhaps ask for 37 or 38. You have a nice csr...and I'd hate to see it go for less.
