I emailed with them for a couple months earlier this year (probably May-July). I was getting close to flying out to see it ... then I bought a Scion FR-S instead.
I loved the idea of having a RHD JDM 3rd gen though...and the 4age with LSD rear didn't hurt one bit.
That said, some things I was unsure of: there are no side GT-R decals. Leading me to wonder if it had been repainted. If it had been repainted...it could be hiding bodywork and not be quite as mint as it looks. Difficult to get a good handle on from multiple states away. Started looking for a reputable company to inspect it...but didn't quite get that far.
The pictures I got of the underbody were decent for the year....but didn't seem as flawless as the rest of the car. That said, they were sent from a cell phone and weren't high res (about thumbnail size almost!), making it hard to really tell. I'm not suggesting that the underbody is in bad shape, I just couldn't tell!
But in the end, the biggest factor was that as much as I love the idea of having it...it probably wouldn't have been smart. I already have a project '67 Datsun Roadster. And my daily driver is my '00 Celica.
I thought it'd be more responsible to buy something newer and keep the '00 Celica as my winter car. Hence going with the FR-S...which I really like...part of me would still really, really love to own this car instead though. And that engine bay is so clean!
Hopefully it finds a good owner one of these days who will appreciate and care for it properly. (Better than I would have been able to).
