The BMW E23 7 Series stands as an iconic luxury sedan that defines an era of automotive excellence. From 1985 to 1989, these vehicles not only delivered impressive performance but also enveloped occupants in superb comfort and lavish styling. Imported to New Zealand, the E23 models signify the pinnacle of 80s engineering marvels, celebrated for their powerful inline-six engines and an array of advanced features, including ABS brakes and trip computers. However, like all venerable classics, these 7 Series sedans deserve specialized care to ensure they remain in prime condition, allowing owners to relish their investment's exquisite blend of luxury and performance.
Common issues for the E23 7 Series (1985-1989) include: Rust around the wheel arches, sills and undercarriage, coolant and oil leaks from the engine, failing automatic transmissions, worn suspension components (especially the self-leveling rear suspension), and electrical problems (short circuits, faulty sensors). Instrument cluster pixels may also fail. The air conditioning system can be problematic and expensive to repair.
WOF tips
During a WOF inspection, particular attention should be paid to rust (structural integrity), brake condition (lines, rotors, pads), suspension components (worn bushings), and electrical systems (lights, wiring). The self-leveling rear suspension can be a WOF concern if it is leaking or not functioning correctly. Make sure all seatbelts are functioning. Check for power steering leaks. Tyre condition is also important.
