The list of cars so far is pretty decent plus they are going to anounce at least 80 more I'm sure there will be more then enough cars that I like. Plus if I get the standard edition of the game it will probably take a long time for me to get most of the cars. I still don't have most of the cars in Forza 3 and 4, I have almost all the cars in Horizion except for the 1962 Ferrari 250 GTO but I'm close to getting it since I got more then 1/3 of the credits needed to buy it and I got all the cars in Forza 2 but I the main reason I did that because it had achievements attached to it. My guess is that Forza 6 will have at least 400 cars since it most likely will have all the cars from Forza 5 including all if not most of all the DLC cars and a fair amount of new cars I'm also hoping they will also add some unicorn cars which are missing in 5.
