The BMW E23 7 Series, especially the 735i from the 1985-1986 model years, redefined luxury sedans with its unparalleled combination of performance, comfort, and iconic styling. Imported to New Zealand, this vehicle not only elevates driving experiences but also showcases the brilliance of 80's automotive innovation. As an owner of a 735i, you possess a piece of history, yet it also necessitates dedicated care to continue delivering the exceptional performance it was renowned for.
Common issues for the E23 7 Series (1985-1986) 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.
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.
The E23 7 Series shines with its offering of a comfortable ride, opulent interior, and its remarkable inline-six engine. It was ahead of its time, boasting features like ABS brakes and trip computers, enhancing both safety and convenience. Maintenance can become a complex task when considering the age of your 735i and the intricate systems it employs. Common concern areas include the cooling system, which often requires attention around 150,000km: the water pump, thermostat, and radiator should be inspected to avoid overheating issues. This naturally links to our Cooling category for essential parts.
Additionally, rust can be a significant issue, especially around the wheel arches and undercarriage. Regular servicing of the automatic transmission and suspension components is crucial too. Don't overlook common wear items like brake pads and filters—consider our Braking category for braking components and our Filtration category for replacement filters to keep everything running smoothly. Ensuring these systems are properly maintained will enhance not only your driving experience but also the longevity of your classic 735i.
