What's funny is people complained about those redundant models when GT2 was released, and they're still complaining now. Kaz has said in an interview that back when GT was in creation (mid '90s) Japanese drivers knew of all the differences in the various models, and since GT is a Japanese game, it was easiest for PD to implement all these "repeat" models, because they actually did make a difference to the Japanese gamer at the time.
But he admitted (sorry if this is a spoiler, jeff) that especially in GT5, this idea is basically outdated in today's world. He seems to be wishing he could have done things different.
Personally, I say more is better overall. I'd rather have more cars than less. But it wouldn't hurt if (in the future games) they could just focus on adding the tons of American and European cars that made a difference. Maybe even introduce the world to a Skoda or something made in a former communist country. I would drive it!
Skoda (we say koda here) would be a nice adding.
Especially Felicia from 90's (very light and agile car to some 50 mph) is my favorite. It only needs harder Shocks.
Drove 3 Felicias, and i was dreaming that one day..maybe even in Gran Turismo

So the Kit-Car version.
Only in GT2 was Skoda just mentioned briefly in VW description.
And agree too, that adding more everyday cars with the option to tune it to some 3 - 5x power with RM would be VERY nice.
Because of this i like GT2 most. BTCC cars from that era was something other than NFS or else had.
Its good to have Lambos, Ferrs, McLarens, but we (or i) need some more normal cars too in GT5/6.
Im seeing GT as a guide to evolution of car (or their manufacter) developing throughout years.
Not only the newest cars and most powerful cars i seek in GT.
But there is a problem with intersection time, money, licencing problems and sales.
How incredibly awesome would it be for Polyphony Digital to re-release GT2 with an online mode, 16 car grid for online races and make it available on PSN?
We could have BTCC/JTCC/ATCC/etc touring car races. There would be epic Le Mans races (even without Le Mans). The list of awesome goes on if that happened.
hey, i was about to start a thread about GT1/2 online mode as a bonus part of next GT :-)
