People sometimes forget that those "standard" cars were made back in 2003 to 2005. You can´t change what they are or say that "they have poor quality"...remember when we saw GT3 and GT4 at that time and probably said "wow the cars look so real!!"...now we are bitching because we still have them...and that is the real "problem"...not how the models are compared to the "Premium" or as I prefer to call them..."the newer more actual" ones.
But if you think about it...PD had and still has a lot licences for those cars...if they get rid of them we will loose tons of great cars as well some repeated cars (this is the second problem not just the old quality).
Turn 10 got rid of 200 to 400 cars in Forza 5 and a lot of people got mad...imagine what could happen in this community if we loose the Supra, Toyota GT One, and some others...
PD doesn´t want to do that...they are preserving these models (and the respective licences for sure) for maybe in the future make newer models from them...or maybe not...who knows.
I won´t be worried if we keep one model of each car getting rid of all "duplicates"...or maybe they can put 2 to 3 versions of each, one example Subaru Impreza (no STI, the cheaper version) and the STI version. Or as in other models put a gasoline, diesel and then the expensive version...(example: Mercedes Benz C 230, C330 D-diesel- and then C63AMG/Black Series).
They are not clever enough to do something like this if they want a massive car list without so many Miatas and Skylines.
Also same with years...put the years in where the cars make substantial changes to the model...like a great example with BMW 3 series:
E21, First generation, 1975–1983
E30, Second generation, 1981–1994
E36, Third generation, 1990–2000
E46, Fourth generation, 1998-2006
E90, Fifth generation, 2005–2012
F30, Sixth generation, 2012
6 basic cars...add diesel versions you make 12, add M versions. Done. Is it so hard to think like that?
I can live with M versions alone though...and Racing versions.
