While you are rolling down the road with large luxury gauges staring back at you, feel free to grab a gear and hold on! This 1970 Buick Riviera is powered by a carburetor Big Block 455 CID GM engine that is tossing all of this power to the ground via a Turbo400 3-speed automatic transmission. This 1970 Buick Riviera big block purrs through dual exhaust pipes with subtle and appropriate chrome tips popping out from under the large rear chrome bumper. From behind all of the lookers can see is that awesome 1970 Buick Riviera dome style rear glass.
