A good number of Speedsters have passed through my hands so I will chime in. Your VS is absolutely stellar in every particular adding to that the engine just puts it into a unique category all by itself. So how do you put a number on this speedster is the question and IMHO it is what ever you can command for it and that said, I would price the VS as a very clean car then add to that the engine value... Can you put a value north of $36k plus perhaps as all you need is one person who has done their homework and knows the "one off" value of what you have . ...... Your other option is to remove and replace the 356 engine with a decent size VW engine and sell the 356 by itself. Either way the speedster is a beautiful representation Scott !
