1953 BUICK ROADMASTER SERIES 70 SEDAN 4-DOOR
"50TH ANNIVERSARY OF BUICK" First model to have V8 (see the hood ornament "V" for that representation) and power steering and 12 volt power system from the factory.
This car is ALL ORIGINAL except the fan blade was changed to an aluminum FlexBlade to push more air in slow speeds (parades) so the vehicle would not overheat. Otherwise all 1953 factory. 4 new Coker Classic White Wall Tires. Original V8 chrome hubcaps.
The right passenger door, lower section has a mark from backing it out of our driveway too close to the building. It also has paint chips at the hood to side fender where they meet. A mouse ate the fender welting where it meets the back trunk area (see photo)
