GT4 is by far better than many of the console racing simulators before and after it for quite a while, and it is an un-arguable subject, trust me.. you'd be disagreeing with a gigantic majority.
Anyway, my new skyline:
Brand new, black and blue semi-pearlescant paintjob. Naught to 60 in 3 seconds (yes, 3 freakin' seconds.) Tops 240 on the high speed test track. Sounds (and goes) like the might of four jet engines put into a package of pure badass-ness. It's been fitted with nearly every customization part available and handles like a slot car.
