Fuel use varies by engine choice. The base V6 delivers solid economy for the size, while optional V8s trade some miles per gallon for stronger pull. Highway figures improve with overdrive options in later years. Unleaded fuel is required after catalytic converters arrive.
Servicing stays simple with conventional layout and wide parts availability. Regular oil changes, filter swaps and ignition tune-ups keep the Rocket engines running strong. The body-on-frame design allows easy access for most maintenance tasks.
Safety equipment centers on standard lap-shoulder belts, front disc brakes, dual master cylinders and an energy-absorbing column. Side marker lights, backup lamps and a starter safety switch round out the basic kit. No star ratings appear in period tests.
Keeping the car means watching for rust in the rockers and frame, plus routine fluid checks. Clean examples hold up well thanks to durable powertrains and straightforward mechanicals. Parts remain common through the full production span.
