No Skyline/GT-R is ever Uncool or worse to me. I'm going to say Cool, but a very slight one for this Skyline. I do remember the racing variant of this car in Gran Turismo 2. You know- the one with the Tomica sponsorship on it.
Those are some awkward proportions going on there. And the rest of the car is very 80s Japanese, that is not a good thing. I'm sure it was a decent steer that makes up for some of the poor styling. Meh.
