Rob,
Why would you consider that? By time you sell your car as is then pay for a completed SPF, you'll take a HUGE financial hit. Not to mention the car probably won't be done exactly the way you want it. So you'll spend even more $$$ changing it to be what you want. Trust me on that one, I've got experience.
Finish your car, then decide what to do with it.
If you must check out the SPF, they are beautiful cars. Jacks' car is really nice and is local. Also, Bob Marshall has an SPF. He lives in Newtown Square. His car was the silver and black one, and it has a 514 in it. I'm sure either one of them would be happy to show them to you.
