Fuel economy averages 9-12 MPG in mixed driving
The big 455 V8 delivers strong low-end torque for smooth highway cruising but drinks fuel heavily, with mixed driving typically returning 9 to 12 miles per gallon and city use often dropping into single digits.
Servicing follows standard GM full-size practices of the era, with a comprehensive factory shop manual covering engines, brakes, suspension, and accessories. many parts interchange with other B-body models like Bonneville and Catalina for easier upkeep.
Safety kit centers on the required 5-mph bumpers, power-assisted front discs, energy-absorbing steering column and padded surfaces, plus the seat-belt interlock that blocks starting until front occupants buckle the combined lap-shoulder restraints.
Keeping the car means watching for rust in quarters and floors while relying on shared GM components. convertibles need extra care for the power top and vinyl materials to stay roadworthy as classics.
