The BMW E12 series marked a significant milestone in automotive history, embodying a revival of style and substance for BMW. A stunning creation by designer Paul Bracq, this model elegantly blended aerodynamic lines with executive appeal, making it a popular choice among New Zealand professionals once it was introduced locally in 1974. With its engineering prowess and rich heritage, the E12 has become a timeless symbol of driving excellence.
Common issues include rust, particularly around the wheel arches and sills. Fuel system issues are possible, especially on the carbureted models, and electrical gremlins can crop up due to age. The suspension components, particularly the bushings and ball joints, need regular inspection and replacement. Keep an eye on the cooling system to prevent overheating, a common issue with older vehicles.
WOF tips
WOF inspectors will pay close attention to rust in structural areas. Suspension components, including ball joints and bushings, are critical WOF items. Brake lines and hoses need to be in good condition, free from leaks or cracking. Headlights and taillights must function correctly, and the overall condition of the body must meet WOF standards. Exhaust system leaks will also result in failure.
About the BMW 5 518
The E12 boasts a distinctive character, from its beautifully proportioned exterior to its well-appointed interior, ensuring comfort and style on every drive. Most models were originally equipped with carbureted engines, transitioning to fuel injection in later versions for enhanced performance and efficiency. However, as these vehicles age, certain components often require attention. Regular inspections should focus on the cooling system, especially around 150,000km, where elements like the water pump, thermostat, and radiator are critical to prevent overheating.
