We all know there's always someone faster. However, given it's a GT-R, the facts remain that it is damn fast for a street car with a lot of well done amenities. So the fact that he talks like that, should be expected as it can deliver some respectable numbers. Especially since a vast majority of people who talk the same shit back, drive cars that are no where near as nicely packaged. All pussy feels good in the dark, but the true test is when the lights are on.
The real question in terms of respect have nothing to do with the car; it's whether he can deliver the ass whooping with said car.
