I am not sure I fully understand
Believe it or not. Some people buy cars as status symbols (not saying the OP did) and that is all they care about. It sounds like the OP is just not mechanically inclined and is looking for assurance that he didn't do any harm to his new car. The fact that he is here asking questions gives him a lot of cred.
