First introduced as a personal luxury car, Buick took their Riviera, offered bigger engine displacement, and the “Gentleman’s Musclecar” was born. Over 1.1 million Riveras were produced from 1963 to 1999, and perhaps the most memorable versions were the early seventies’ boattail styles seen from 1971-1973. Seen here, this two-tone green Riviera has the big 455 cubic inch engine topped with a four-barrel carburetor. The engine compartment is loaded with goodies such as power steering and brakes, as well as air conditioning. The interior is in remarkably well-preserved condition with medium green cloth fabrics and matching door panels and dash. The odometer shows 30,462 miles; perhaps giving reason for the fine original quality throughout. It also features cruise control, power windows and power seat. This is a prime example of Buick’s successful, powerful and memorable boattail Riviera.
