I've been approached at gas stations, rest stops, grocery stores, etc. It's usually someone that thinks they know about cars and doesn't know crap. But, I have also had a lot of people ask what kind of car it is and say it looks really cool.
Far too many times have I had some idiot tell me I should've bought an STI or ask if my car has a turbo. I've replied numerous times "all WRX's are turbo" only to be met with a blank stare.
