Nissan Skyline 350 gt - da'fuq!?

[C.A.R.]

Jap spec r35 also the same as the Infiniti g35 iirc

Almost, the Infiniti was a 'G35' chassis whereas the Nissan equivalent is a V35, but for all intents and purposes they are the same thing. There was no 'GTR' version of the V/G35, it was merely a luxury coupe. Think of it more as a Nissan Primera Coupe and you're on the right track. The numbers refer to the engine size. A 250GT - 2.5 liter. The 350GT - a 3.5 liter.

Quite a bit different to a 350Z really, based on the same platform but that's pretty much where the similarities end.

As for the UK cars, quite a lot of them are Nissan models as I don't *think* the Infiniti was marketed over here (Infiniti being a luxury brand of Nissan, like Lexus is to Toyota...).
