Safety Ratings:
Specific crash test ratings from major organizations for this era are limited or may not have been consistently applied as they are today. However, it was engineered to meet European safety standards of the late 1980s/early 1990s.
Active Features:
Anti-lock Braking System (ABS) was standard or optional depending on the specific market and trim level.
Passive Features:
Reinforced safety cage, energy-absorbing crumple zones, three-point seatbelts, driver-side airbag (often optional or introduced later in the production run), rear seat restraints.
Infotainment:
Basic infotainment system for its era, typically including an AM/FM radio, cassette player, and potentially a CD player as an option. Speaker systems would be rudimentary by modern standards.
Driver Assistance:
Limited. ABS was the primary electronic driver assistance feature. Cruise control was common. No advanced driver-assistance systems (ADAS) like adaptive cruise control or lane keeping assist were available.
Connectivity:
No modern connectivity features like Bluetooth or USB. Communication systems would have been limited to optional car phones if fitted.
Lighting:

Typically every 10,000 - 15,000 km (6,000 - 9,000 miles) or annually, depending on driving conditions and oil type. The manual will specify exact intervals and oil grades.
Timing Belt Replacement:
For V8 engines with timing belts (some variants might have chains, but early V8s often used belts), replacement is crucial, typically around 80,000 - 120,000 km (50,000 - 75,000 miles). The manual will confirm the specific interval and whether chains or belts are used.
Engine Oil Type:
