put it this way, a client got a 32 GTR for a very cheap price imported (not through these guys so don't jump to conclusions) and upon arrival it had so many problems...when he had it inspected it turns out his GTR was actually made up of 3 cars welded together (front, rear, mid sections).
So I guess you might have a very very slim chance that this is a legit importer, but there being no quote on quality, I would take the prices with a huge bit of caution.
If you're going to import a car which is usually sight unseen (with your own eyes) then you have to at least trust the people who say they've inspected it and given it the all clear. Paying a bit more for peace of mind is worth it.
