Am I really the only one who (only) cares about sports cars, exotics and race cars? I feel like a lone wolf...
oh well, I could be
always outnumbered (but) never outgunned 
.
Yeah! I said it finally!
I'll support thy my brother against this infidels!!!
Seriously. I like that there are common cars in the game, but it sucks that they're the most part of it.
Sure, what people love about GT is that they can drive their Honda Civic in the game. Fair enough, I see your point, pack in, say, a Mazda Miata. Alright, pack a Miata from each generation of the car so you can be more specific. But why the huck do you need 34 Miatas? !!! For crying out loud, the car has only three generations!!! Yes, it's quite a succesful and iconic car but it can be worth more in-game representation that Ferrari, or Le Mans cars.
What about following the following model for including cars:
-Car X
*Prototype.
Generation #X:
*Base model.
*Highest trim/performance stock model.
*Odd or remarkable factory model (Say, a limited, and noticeably limited, edition or concept car)
There you go. It's still varied, but not annoyingly extense. Maximum of around 4 or 5 cars per generation. Of course, exceptions could apply but this is the rough idea of what it could be.
Also, I frankly don't care much for K-Cars. If some people like them, fair enough. But as they're a reduced crowd, K-Cars should have a reduced share of the car list. Yeah, every car should be premium, but some more than the others.
Someone in this thread said already, How many people you know that own X exotic car. Yeah, not many. They all drive crappy commuter boxes. But I'll ask you: how many people WANT to drive X exotic car? Games are the places for fantasy, I couldn't care less for boring/stupid/electric/economic cars in my fantasy games.
To all those who don't want Kei cars and the like in a game they are playing, just go play NFS.
Shut up. What if I want a console game that's entertaining but with great driving physics and graphics? It seems like the majority shares the thought of "Axe the boring cars, get in more exciting stuff"...
