I think that there'd be no point in 1321,213,21,321,321,651,632,1324,213 cars.....think about it.....how many will you acctually drive...
Take GT4 for example....Whats the point of haveing a Ford Model T Tourer....
too look cool? makes you sooo special....I think that there shouldnt be 20 variations of the same car(Skyline for example: GT-R, GT-R Vspec, GT-R VspecII, GT-R Mspec, GT-R Mspec Nur, GT-R VspecII Nur, GT-R Vspec N1, GT-R Vspec Special Color MNPpointless car.........)
If anything there should be a noticible difference between the cars like that...
But my guess is that they should have anywhere between 700-800 Useful Cars
