First of all, what a gorgeous car!
Without getting into dollar amounts, I think you could a wide variance depending upon how quickly you may need to move on the deal, right?
I recently heard someone say that there are three (general) types of car sellers in the collector world:
1) those who have no idea what the car is worth and ask/take too little;
2) those who know what the car is worth and ask a reasonable price, market it properly and let the "market" sort out the price, and;
3) those who know what their car is worth, have little intent on moving the car unless some sucker comes along with deep pockets.
I say there's a 4th type: one that has a dillisional value in their head and sets the price way over what reality suggests.
I'm just speculating that based on the caliber of car you own, you probably have a pretty good idea what you have and its simply a matter of fine-tuning the number and putting it out there. Definately not suggesting that you fit into any of the aforementioned categories
Your car looks like it is of the caliber that may attract the interest of some real global consigners (such as Fiskins). You may have to take a hit off the top to get hooked up with the right buyer, but I'm guessing that these guys have a short list of people who want exactly what you have....and will pay you properly for it. Too nice for eBay and CL that's for sure.
I know your question wasn't "how should I market this car", but the two are sort of interrelated in my mind.
