I missed that obvious quirk in the equation.

I think Gogar's comments are realistic and to the point.

I think the Sporto build relegates this E to a driver status only. There may be a Sporto nut out there who wants a tangerine '71 E, but are you willing to risk that? If funds are tight sitting on a $30k restored 911 could be painful if you really need to sell it. I'd be very careful with the amount of money I spent on it to avoid a resale problem. I'd probably restore it as a 5 speed to increase my available pool of buyers, but include the Sporto parts as a bonus to help with the sale.

At this point I'd try to calculate the money you have in it and sell it with full disclosure (if the buyer is not a hard core 911 guy who knows the build info). It's a tough economy, but you should be able to get your money back at least.
