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

2 to 3 times a day, if they don't knock on the door they catch me in the garage or on the street, one guy wanted to trade me two chevys for the scamp when I told him they was the wrong brand he said his brother had two 69 mustangs he could trade the chevys for and I told him still the wrong brand, a few people got pissed when I told them it wasn't for sale at any price, one guy told me everything's for sale, I told him not everything is because the scamp is not.
