Sometimes you think the new car smell has gone, but your nose has just gotten used to it. I've owned new cars in the past where I thought the new car smell was totally gone, but then a new person gets in the car for the first time and comments on it still having that smell.
The new car smell in my Corvette was really strong for about the first 6 months but now I don't notice it anymore. I should ask my wife if she still smells it, as she doesn't go in it as often as me, and she really dislikes the new car smell so if it's still there she would know.
