Seatbelts:
Three-point inertia reel seatbelts
Rollover Protection:
Integrated roll bar structure for GTS models
Audio System:
Period-correct cassette player and analog radio, often with aftermarket upgrades available.
Features:
Limited driver assistance features; focus is on driver engagement and mechanical feedback.
Features:
No factory connectivity features (e.g., Bluetooth, USB).
Oil Change:
Every 5,000 km (3,000 miles) or annually, whichever comes first
Major Service:
Every 15,000-20,000 km (9,000-12,000 miles), including timing belt replacement (critical!)
Engine Oil:
API SG, SAE 10W-40 or 15W-50 (check owner's manual for ambient temperature suitability)
Coolant:
Ethylene glycol-based antifreeze, 50/50 mix with distilled water
Brake Fluid:
DOT 4 (high-temperature synthetic)
Timing Belts:
Crucial to replace timing belts at recommended intervals (typically 30,000 miles or 5 years) due to non-interference engine design, preventing catastrophic damage. Belt material degradation over time is a common issue.
Fuel System:
Degradation of K-Jetronic components, fuel line deterioration, and injector issues can occur with age.
Cooling System:
Aging rubber hoses and radiator components can lead to leaks.
Electrical System:
Aging wiring looms, switchgear, and grounds can cause intermittent faults.
Timing Belt Kit Example:
Refer to specialized Ferrari parts suppliers for correct OE or equivalent part numbers for timing belt kits (e.g., Gates, Dayco may offer aftermarket)
Legacy:
Ferrari's legacy in producing iconic mid-engined V8 sports cars, continuing the lineage from the Dino 246 and 308 GT4.
308 To 328:
The 328 was an evolution of the 308, featuring a larger displacement engine, updated styling (particularly front and rear fascias), improved aerodynamics, and minor interior revisions. The 'QV' designation signifies the move to Quattrovalvole (four valves per cylinder) for the 308.
Production Years:
308 QV: 1982-1985; 328: 1985-1989
Production Numbers:
Significant production runs for both models, with the 328 being particularly popular.
