Story
1963 Buick Riviera
The first Riviera was one sharply drawn, pillarless four-place coupe. Buick made the 325-hp 401 standard and added a 340-hp 425 after launch; both belong on this model-year page.
What makes it a 1963
The series-7 VIN, Fisher style 63-4747, BUICK deck lettering, and medallion taillamps establish the starting point. Engine, axle, paint, trim, and options still require car-level evidence.
