Sell the car, youre to young to deserve it and you sound like a snob . JUST KIDDING!!! We all deal with this to some extent. I live in central Missouri where the "bogans" are predominant. Hell if you dont drive a rusty pick up and have all your teeth you wont fit in. Even had one of them toss a rock at my crossfire while I was parked WAY far away from everyone else at work, see my gallery, they just wont get it.
My brother always says,"the best revenge is living well" and my wife says, "don't let them get to you because then they win". Smile, wave back and know your successful and they will be doing the same stuff 15 years from now, perhaps even employed by you One suggestion, watch where you park cause thats when the chicken #$@! will do the most damage.

Great luck and welcome to the forum!
