This matching-numbers 1965 Buick Riviera Gran Sport is powered by a 425ci V8 engine mated to a 3-speed automatic transmission with a 3.42 posi-traction rear end. The engine features dual-quad carburetors, aluminum valve covers and a chrome air cleaner. The exterior features working clamshell headlights and Gran Sport badging. It also has ribbed rocker molding, Soft Ray factory-tinted glass and a complete spare tire with a jack. This car retains its original engine and was born with an LX-code, VIN-matching engine and an original BS-coded switch-pitch SP400 transmission. This Gran Sport has stock original Rally wheels and whitewall tires. The deluxe interior is equipped with additional features that include an aftermarket AM/FM radio with power antenna (with the original radio included), along with Buick floor mats, a tilt steering column, power windows, period-correct aftermarket air conditioning, quick-ratio steering, a Buick trunk mat and a rear-seat center armrest. The car has been owned and maintained by a collector for the past 14 years. Prior to that, it was owned by the same family since new. This Riviera Gran Sport is registered in Connecticut, was there from 2010 to 2017 and has been in California since then. The late Dick Sweeney, a recognized 1965 Riviera Gran Sport expert from the Riviera Owners Club and Buick Club, inspected this car and confirmed that it is an original, stock Gran Sport, as said in a 2012 e-mail included in the sale. This car also comes with the original owner's manual and Protect-O-Plate.
