The BMW 5 Series (E12) from 1979 to 1981 represents a landmark evolution in the BMW lineage, seamlessly merging sporty handling with sophisticated executive comfort. Revered by Kiwi motoring enthusiasts, this model exemplifies engineering excellence and timeless design. Its distinctive presence on New Zealand roads speaks to a legacy that's more than just a car; it's a passion enjoyed by many.
Common issues for the 1979-1981 BMW 5 Series include rust (especially around the wheel arches, sills, and floor pan), fuel system problems (related to age and ethanol in modern fuel), aging suspension components (bushes, shocks), and electrical gremlins. Keeping an eye on cooling system health is crucial to avoid overheating the engine. Specific models may struggle with vacuum leaks leading to poor running.
When getting a WOF, pay close attention to rust, especially near structural areas; ensure all lights are functioning correctly, as this is a common failure point in older vehicles. Check the condition of the tyres, brakes (pads, rotors, and lines), steering components (play in the steering wheel), and suspension (excessive movement or worn bushes). Exhaust systems are notorious for corrosion, so ensure its integrity and emissions meet standards.
The E12 5 Series boasts a range of responsive engines and a well-balanced chassis, offering variants that can suit various performance needs. As with any classic, regular maintenance is essential to preserve its performance; common replacements include brake pads, suspension components, and, importantly, parts of the cooling system. The recommendation is to check the cooling system at approximately 150,000km, which involves inspecting the water pump, thermostat, and radiator hoses for any wear.

In addition, watch out for signs of rust, especially in coastal areas, which can affect the wheel arches and floor pan. The interior, while comfortable, will also experience wear over time, so it's wise to keep an eye on upholstery and trim. Braking components, such as rotors and pads, should also be serviced regularly alongside the oil service and air filter replacements, aligning with general vehicle upkeep.
