The link is to a Norwegian car export company. The page doesn't show the chassis number, so it appears that Bret contacted them.

Just to illustrate how poor our identification method is...

Using the equipment detail method:
The mirror backs and roof antenna base are not black. The dash inlays behind the speedometer and on the glove box are wood grain instead of black. The valve cover is copper color.
But it has the split front bumper, fog lights, hood vents, rear quarter panel vents, and body color trunk hinges.

Using the paint and body color method:
It's not orange, white, or blue, with black hood, tailgate, and racing stripe down the side. And the engine compartment is a nice shade of plumb.

But looking around at the rest of the website, something jumps out. They have another Bellett they are offering, which looks more like a GTR, but they are not identifying it as a GTR, and they are selling it for 25% less than this car:

This car is orange, and looks like a twin to the New Zealand car. Black hood and tailgate, but missing the black on the fender tops and the base of the windshield, and no racing stripe on the side. Chrome back mirrors and antenna base. Black inlays in the dash instead of wood. Split front bumper with fog lights, hood vents, and rear quarter panel vents. Red valve cover on a DOHC engine. The engine compartment paint matches the body color.

So why is the car that looks more like a GTR presented as a GT with a lower asking price?

Does the Norwegian know the little spot or detail secret that the Japanese aren't sharing? Or is he working with a Japanese agent who knows the detail and forwards the information to him in Norway?
