The third-generation De Ville of 1965 to 1970 brought sharper body lines, vertical headlight pairs and a perimeter frame in place of the X-frame. For 1968 the 429 V8 gave way to a 472 cubic-inch V8, and the grille took a finer mesh. 1968 was the last year of the stacked dual headlights. You're looking at a 1968 De Ville convertible lowrider with custom paint.
