Audio System:
Basic AM/FM radio, often with cassette player. Aftermarket upgrades are common.
Climate Control:
Manual heating and ventilation system. Air conditioning was an optional extra.
Features:
Limited by era. Primarily focused on the driving dynamics and mechanical feedback, rather than electronic driver aids.
Features:
N/A - No modern connectivity features like Bluetooth or USB were available from the factory.
Oil Change Interval:
Every 7,500 miles or 12 months, whichever comes first (typical for the era, always verify with the manual).
