Arguably, the Dodge and Plymouth Mopar cars were at the forefront of this movement with head-turning High Impact paint colors and more unusual options like the one we'll be discussing today. The Mod Top option added one of three vibrant floral print patterns in place of a solid-color vinyl roof, and could even be extended to the interior upholstery.
