Crash Test Information:
While specific ECE or NHTSA ratings for E30 Touring/Convertible are not readily available, the E30 chassis was known for its robust build for its era.
Braking System:
Front: Ventilated disc brakes; Rear: Disc brakes (solid or ventilated depending on model/year).
ABS:
Optional on many models, standard on later high-performance variants.
Seatbelts:
Standard front and rear seatbelts (3-point in front, 2-point or 3-point in rear depending on year/trim).
Body Structure:
Reinforced safety cage, crumple zones (designed to industry standards of the time).
Audio Systems:
Factory fitted radios (e.g., BMW Bavaria C series), cassette players, and speakers. Upgrade options likely available.
Advanced Features:
Limited by era; ABS was optional. Features like cruise control were available on higher trims/later models.
Original Connectivity:
None in the modern sense. Focused on core vehicle operation and driver experience.
Oil Change Interval:
Typically every 10,000 - 15,000 km (6,000 - 10,000 miles) or annually, depending on driving conditions and oil type used.
Timing Belt Replacement:
For M10 engines (if equipped with timing belt), typically every 50,000 - 80,000 km (30,000 - 50,000 miles). M20 engines use a timing chain which is generally maintenance-free for the life of the engine.

Recommended: API SG or higher, SAE 10W-40 or 15W-40 (specifics depend on climate and engine).
Coolant Type:
Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. BMW specifies certain coolant types (e.g., G48 compatible).
Transmission Fluid Manual:
API GL-4, SAE 75W-90 or 80W-90 (e.g., BMW MTF LT-2 or equivalent).
Transmission Fluid Automatic:
Dexron II or Dexron III (e.g., ZF 4HP22 requires specific ATF).
Common Problems:
Cooling system leaks (radiator, hoses, water pump), fuel pump failure, alternator issues, seized heater cores, worn suspension bushings, rust in common areas (wheel arches, rockers), idle control valve issues.
Maintenance Focus Areas:
Regular inspection and replacement of cooling system components, diligent rust prevention, and proper fuel system maintenance are critical for E30 longevity.
Bmw Legacy:
BMW's history of producing driver-focused, sporty sedans and coupes.
