Saw black 135i yesterday on 93 South, seemed unaware I was next to him in same car.
Saw black 135i today on 93 North, dude looked like a european car salesman (no offense in you're on these forums buddy!). Also unaware.
Saw silver 135i on a random trip to Marlborough. Yep, unaware as well.
The more these cars pick up in popularity, the smaller the chances owners are forum member 1'er fanatics.
