The money comes from somewhere .. I have both those type people in my life. My x works for usps. Makes good money. But not that good. Got a buddy that is a dang good Ford diesel tech. Makes 100k year. Both these people.I speak of have nice homes and drive new vehicles . neither one have the budget for 4.20 cars ... Got another good buddy owns his own body shop. In a small town. He has a 4.70 BBC Fox body. His 18 yro son has a 4.50 67 camaro. They bring them to the track in a diesel pusher motor home and a 75k stacker trailer. Great family and good racers. And they drive new.vehicles and have a very nice home. Usps worker, tech at dealership yes make good money . but they got a honey hole somewhere.
