Haha, I do that sometimes myself.

1) Finance
2) High 20s
3) NorCal
4) Not out of the blue - but whenever I meet people my friends tend to let it slip at some point. I don't mind people talking about it and answering questions if they ask me because I do love talking about it, but I don't go out of my way to tell people I have one if that makes sense. I bought it because I love the car, not to show it off (hard to shake that image though especially given my age).
