I definitely get some attitude, but it depends upon where I am driving my car. In Vail, which is defined by third and fourth homes priced in the multi-millions, no one cares. Ditto for Denver's Cherry Creek area.
But in Boulder (defined by rich white liberals), people seem to think I'm a spoiled prick. (although I'm in my early 40's I look ten years younger, which adds to their "impression" of me).
What they don't understand is that the car was purchased on Craig's List for a mere $3000.
Yes, "stinky" is a ratty beast! But unless you know these cars, the people in Boulder who look at it from ten feet away, think, wow, that "kid" is driving a Porsche! What a rich, spoiled jerk!. That being said, I've exchanged a few waves with other P car owners in B-town.
