1948 Buick Series 70 Roadmaster Navigation
The 1948 Buick Roadmaster Convertible was a pre-war design but it received the famous Dynaflow transmission, which was the first torque-converter automatic transmission on an American-built car. The engine is a 320.2 cubic-inch, in-line eight with a power rating of 144-150 hp.
Known for interior luxury and quiet operation, there were few other cars like them of this era. The sleek styling of these particular two-doors elicited an emotional response from the motoring community that surpassed the expectations of GM.
This is a low mileage car that has benefited from a frame-off restoration. It is equipped with hydraulically operated push-button controls for the top, windows and front seat.
