6. Cale Yarborough's 1973 Chevrolet Chevelle
One of only two drivers in NASCAR history with three consecutive championships, Cale Yarborough ran his first full season in 1973. He finished second in total points, a feat he'd match in '74. His '73 Chevrolet Chevelle with Kar-Kare, an automotive supplies dealer, sponsorship cut a bold stance with orange base and white hood and roof.
