How often does someone ask you to sell your car to them?

i have a 72 twister........... went into advance last night, and as i come out, some guy is standing near my car. as i walk to my door, he says " wow, how much you want for that bad azzzzzz cuda"!. i could not help myself. i just looked at him, turned around, got in my car and left. all the while he stood there looking stupid like he was. lmao
