No ginge, TBH i dont think there will be any chages.
Look at the list, car manufacturers from all over the world, more Jap than others, but what you expect, apart from the game being made there, the country having a huge population, and Jap cars being the most popular, they make more sporty models of cars than any other country.
Ive NEVER known a car game to have so many cars from so many countries.
I just had a count thru, and i counted over 90 different cars from UK companys (not including most the Fords as they American models), there of tons of different makes.
That not enough for people?
