Not to be a "negative Nancy", but unfortunately you'll never get nearly that much money for them. Realistically, you're likely get a max of $4,000-4,500 for each (most likely far less than that). There are plenty of cars out there, with more parts, and better engines, that sell for that price or lower.
I'm going to guess that, including the price of parts and labor, those cars cost the owner(s) quite a bit over $10,000 to build. But realistically, unless it has a fully built B-series turbocharged engine, a K-series swap, or a J-series swap, you won't get anywhere close to what was spent to build it.
They look like great cars, for what they were originally intended for. But for your average Honda enthusiast, that's far too pricey. I wish you the best of luck on the sale.
