Like others have said, $40k would see this sold in minutes (to me please) but think it's got to be a good bit more. I can't really comment about how much more as my budget tunes out for higher priced cars!
I do think the fact you are a generous and knowledgeable contributor here (thanks for the advice you have given me), people will add value to the car for that reason - if you decide to sell it here.
