Gauges:
Classic dashboard layout with analog gauges for speed, fuel, oil pressure, temperature, and amperage. Warning lights for various systems.
Cruise Control:
Optional cruise control system available on many models.
None:
No modern connectivity features (Bluetooth, USB, etc.) expected in this era.
Oil Change:
Every 3,000-5,000 miles or 3-6 months (depending on driving conditions)
Tune Up:
Every 12,000-24,000 miles (ignition points, spark plugs, distributor cap/rotor, carburetor adjustment)
Transmission Fluid:

Engine Oil:
API Service SG or SF, SAE 10W-30 or 10W-40 (check owner's manual for specific viscosity based on temperature)
Coolant:
Ethylene Glycol based antifreeze (e.g., 50/50 mix with distilled water)
Brake Fluid:
DOT 3 brake fluid
Rust:
Prone to rust in common areas like fender lips, rocker panels, floor pans, and lower door skins due to age and environmental factors.
Carburetor:
Carburetors can become gummed up and require cleaning or rebuilding due to ethanol in modern fuels and age.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical issues, corroded grounds, and failing switches.
Suspension Wear:
Ball joints, tie rod ends, and bushings commonly wear out, affecting handling and alignment.
Cooling System:
Radiator leaks, water pump failures, and heater core issues are common due to age.
