Im athinking along the line of road going cars. Isn't calsonic the GT car?
And when I say famous I mean accomplished cars, kismo's car is nice but it doesn't stand out. Mines is super fast around track, MCR is fast on the touge, Z tune is uber expensive and rare and HKS one is another mega buck car.
I guess when it comes to color, there are so many more colors that I haven't even mentioned, yellow, millenium jade, MNP 1 2 and 3 blah blah blah but blue seems the most common color for GTR yet not often used in Japanese tuning world
