Game issues, playability, cars in wrong classes!

Hi there everyone, I don’t usually post on here but I feel the need to raise some points about a number of problems with forza 6, verified by playing two games side by side (2tvs and 2 xbox one consoles).
Firstly there is a problem with cars in races that are above the class it should be, 880 for example, doing the Grand Touring races, the Caparo T1 class 952 is racing on here and absolutely storming ahead, no matter what skill level. I normally play on expert to pro level but have to drop down to very easy skill settings and even then, the thing is still flying, obviously because it shouldn’t be there. There is a problem with the rewind function when on endurance races. At about 24 minutes the rewind function fails to show the car rewinding, instead just showing a blue screen with forza on it, it takes you back a short bit and the camera could be at any angle, like facing the car, so when you hit play you have no idea where to turn as you can imagine! The drivatar aggression is crazy, jumping and locking on brakes to a standstill if you follow them in a little bit, totally unrealistic in my opinion. Multiple cars, 6 or 7 plus all moving in unison, really freaky that one! The difficulty settings are very inconsistent, having to change level just about every other race to keep close to some cars, and the usual one car absolutely flying ahead, just like the Caparo T1, except they are within class. There are other issues but I don’t want to look like a complainer, but I have played forza from the start and I think I have valid points on the above issues.
