So I first noticed this when I had my G35, but it happens all the more often with the E92...
I got used to, over a year of driving what people would consider a "nice car", that when I would look at a hot chick and smile at her, she'd generally smile back. I assumed this was just because I was confident and good looking, lol...
So I'm going to some store with my friend in his hyundai elantra, and I see a good looking woman in the parking lot and smile at her.. she sneers back at me, to my surprise. I try to figure out what it is, and the only difference I could figure is the car. Sure enough, all the times I was in my friend's hyundai I got the same results, and everytime in my car I got the same, positive, reaction
It's kinda sorry, but it's truth.... What a world we live in, eh?
