lol nice to see there are a few players in here
M3 is a dick magnet for sure. I always use X5 on a first date, and that is definitely a better image for me as I look serious/mature/responsible.
The M3 is more powerful for me when women are over and see it in my garage. I can remember vividly the look on my most recent girlfriends face when she first saw the M3 in my garage - fear. Fear that I was suddenly more attractive than she thought, and that more women than she thought would be chasing me. Absolutely not true but naturally this fear works in your favor.
