The second-generation Riviera of 1966 to 1970 kept its X-frame but grew longer and wider, with no vent windows. Its concealed headlamps pivot behind the grille. For 1968 loop-type bumpers wrapped around the recessed crosshatch grille and the tail lamps. Shoulder belts for front outboard occupants became standard from January 1968. Here we have a 1968 Riviera, with an automatic gearbox.
