For me it was probably sometime in the Mid 70's, my cousin had a 67 Mustang, a friends brother had a 70 Chevelle SS396 and some other guys had a bunch of Mopars.I lived on the corner and could sit in the chair and every one of them that went around I would sit there and pick them out to my parents by the sound of the exhaust note,then I would get up look out the window to see I was right most of the time. My mom use to get upset because my bedroom walls were covered in car pics. from all the Magazines.
