The reason i said certain years way mainly because the facelifts in my opinion were better
As with the C-X75 i would hope they'd use the one from Rivals.
I took a short cuts on the Skyline frame name, though its doesn't really make a difference to be honest.
The IS 300 was manufactured in 2000 and sold as MY01 so its not any different, so technically 2000 is what it should be.
The Evora GTE whether or not is was made in 2010 the 2012 is the same car.
The Escort RS Cosworth in 1993 was the same car. I don't go by release dates
The Ralliart Colt was released in Japan. They had the Version R .
The rest, it really doesn't matter what year the car is because its the same besides, the developers are going to search for the car anyway so what you and others think or even me is completely irrelevant to them.
