I am rather partial to East City because some of the most interesting cars come from there. (Sorry, Renault Espace F1) There is the Toyota 2000GT, Datsun 240ZG, Nissan Skyline KPGC10, Subaru 360, Tommy Kaira ZZII, Tommy Kaira Rs and M30, the JGTC racers, etc. There is also a used car lot, a unique feature of East City, which provides access to the most elusive cars in the game and other good autos that cannot be found in dealership lineups. The only sour point is that all of this resulted in (and sprang from) the fact that Japanese manufacturers are overrepresented, but otherwise it is my favourite city. The soundtrack also reflects Japan's new culture quite well.
