-Premium cars. Having a proper interior view is ace.
-Online racing. I've not really tried this yet, but the AI in Gran Turismo has always been a bit rubbish. The game just screams out to be played against other humans.

Mclaren F1 Road car - Finally a game with a sim quality version of this!
Real world tracks - Nurburging/Nord, Monza, Circuit de la Sarth - These are awesome.
Premium Cars - In general they are all exceptional and i enjoy them greatly, every Ferrari is beautiful.
The signature edition with the key-fob, usb pendrive, wallet and free stealth and chrome cars!

Without even playing GT5 or any of the GT games, but watching a hundred videos about them, I can already tell that my favourite thing in the GT series is variety! 1st the tracks, man I didn't see such an awesome track selection in any game! 2nd the cars, from slowest to fastest, great variety, beautiful cars! I only miss of course "the cars of my childhood"

Maybe you just got better at it after all those years .
In general one of my favorite GT traits is the variety of the cars. Station wagons, pick ups, rally cars. All ready to create some ridiculous duel scenarios. Now if we could only have twice the amount of tracks to start with...
