If all else fails, take it to the salesman who sold you the car to show you. He probably won't know, but will tell you lies that are kinda funny. Beats talking to the wife!
True story - when I picked up my car I asked him to show me how to turn the fog lights on. He tried and tried until he gave up - seems the RS does not have fog lights, he had no clue.
2nd true story - I asked him why my car was the only one with red door badges, ala redline model. Every time I see him, he has a new story, even though he knows that I know he has no clue. It's become a running joke ...... first it was a mistake by the factory - then he specifically requested they put them on as he thought it would look good (it does!), then they put them on as soon as it rolled off the truck that day - other stories elude me but they get funnier every time I see him
