Not sure if this was posted, or if this was sold recently, but Canepa Design has this car for sale:

The description has some interesting comments in it - not sure how true they are (e.g., first chassis imported to US in 1970). At the bottom of the description is the car's history - it's got quite a heritage.

Canpea also have one of the last Nissan GTP ZX cars, I think it's the NPT-91. Man, I'd love to have that!

It previously had a price tag of $250K on it and was supposedly sold at one point. I wondered what rich idiot bought it, maybe there was no rich idiot...

Its one of those cars that's always for sale for the right price. The new owner raced it a couple times last year as reported by a couple of VARA guys.

I thought I had seen this one before, so that makes sense. Given it's specific focus, I can understand why a car like this would always be for sale at the right price. Unfortunately, that's not my price - I can't afford it!
