The dealer can tell you if it has been redlined
I know this for fact that they can tell since they are trying to use it against me in my quest for a lemon law settlement. BMW Customer Care mentioned that it clearly states in the report that the tech pulled up an over rev code. I did not do it and always break my vehicles in according to specs and inquired a my local dealer. They told me the car was indeed over reved at one point but exactly when is not possible to decipher. I was not the first to drive car and suspect a salesman or prospective buyer did it upon test drive. I hope that that info helps..
