That car is only a few miles from me (Morrisville is just a few miles from Raleigh). I know the story of it from the last couple years. It was for sale on The Samba for quite some time by a guy in Mooresville, NC (about 40 min north of Charlotte). He said he had owned the car for about 2 years before putting it up for sale. He started out at $12K, and after several months he had the listing down to $9K when it disappeared. No telling what it actually sold for.
After that, while searching for a 356 replica online, I stumbled across it for sale (and I can't remember where), but it was one of those big classic car dealerships, IIRC.
Then about a year ago it appeared on my local Raleigh craigslist for sale by this dealership. When they originally listed it, they listed it as a 3 cylinder 1600cc. I contacted them and told them that it was an 1835cc because I remembered that from The Samba listing (and also that it was a four cylinder!). They also said that they had owned the car for most of it's life (clearly a lie, that they removed from the listing after I contacted them to call them on their BS.)
Anyway, I would stay away from this car. It has a dubious history, the aforementioned sag, and the engine bay isn't properly sealed off.
