The BMW E12 5 Series, produced from 1972 to 1981, redefined the executive sedan segment, with the final 1980-1981 models marking a highly refined evolution of this celebrated line. Increasingly rare in New Zealand, the M535 i captures the allure of classic automotive design and the thrilling experience of BMW's performance legacy. These models are cherished by a growing community of enthusiasts who recognize not just their stylish elegance, but the history that comes with every drive.
Rust is a pervasive problem, affecting the bodywork and chassis. Fuel system components, especially fuel pumps and injectors, can fail due to age. Suspension wear, including shocks, springs, and bushings, is common. Electrical issues, often stemming from corroded wiring, can be frustrating. Overheating can occur if the cooling system is neglected.
Rust is a top WOF concern. Brake lines and hoses must be in good condition. Tyre condition (tread depth and sidewall integrity) is crucial. Lights and indicators must function correctly. Suspension components are inspected for excessive play. Emissions compliance is assessed. Windscreen wipers must operate properly.
The E12's standout features include exquisite craftsmanship and a powerful performance profile, making it a favorite among driving enthusiasts. Over time, however, even the best vehicles face challenges. Common replacements for the M535 i include fuel systems, involving parts like fuel pumps and injectors, which are essential to keeping the engine running smoothly. Suspension components such as shocks, springs, and bushings often wear out and typically require attention every 60,000 to 100,000 km to maintain optimal handling. Additionally, be proactive with the cooling system—water pumps, thermostats, and radiator hoses need inspection around 150,000 km to prevent overheating issues. Regular service intervals should also account for brake maintenance; both front and rear brakes are critical for safety, and our Front Brake Service and Rear Brake Service packs are great options to consider.
Rust is a significant issue in these vehicles, particularly in humid areas. Inspect bodywork, especially around sills and wheel arches, to catch any signs early. Fortunately, we offer a wide range of parts and services tailored to your vehicle's needs. From our Cooling category for vital components to our Braking and Filtration categories for essential services, you'll find everything you need to keep the M535 i in prime condition. Connecting with local BMW clubs can also provide invaluable support as you navigate the care of this classic.
