That's a really nice SPF. I'd start taking it to every car show and get-together possible and hope for an impulse buyer. Don't put a "For Sale" sign on it but hang out with the car and maybe someone will ask if it's for sale. Seems like the guy who gets the most for his car is the guy who isn't looking to sell, but gets a walk-up buyer ready to make a deal...
BTW that's just my observation. I have absolutely no data to back it up...
Good luck with it. Again, it's a fine example...
