Ah that leather smell!! I was in the middle of replacing my leather interior years ago, did not have the door panels on yet but did have the plastic vapor barrier on the doors. My leather seats were just installed. There was a car show nearby so I entered, it rained that day so top was up, windows were up, knowing damn well I had no chance to win my class, but just wanted to show it, well low and behold, I won even with no door panels, it was a popular judging show, and many of the folks that voted for my car said when they opened the door to look inside, said the smell of new leather overwhelmed them. And yes even today, 10 years later, it still has that new leather smell.
