The BMW 5 Series E39 is often considered by purists and experts as the pinnacle of BMW's executive sedan, offering a perfect balance of comfort, build quality, and driving dynamics. Replacing the E34, it introduced aluminum suspension components to reduce unsprung weight. The facelift (LCI - Life Cycle Impulse) occurred in September 2000 (model year 2001), bringing the famous 'Angel Eyes' headlights, revised bumpers, and the new generation of M54 gasoline engines. Although the focus here is on gasoline engines (renowned for their refinement and smoothness, especially the inline-6s), the E39 also popularized high-performance diesels with the M57 block. Overall design score: 9/10 (a historical benchmark, but one that now requires collector-level maintenance).
The BMW 5 Series E39 is a masterpiece of Bavarian engineering. With its gasoline (inline-6) engines, it offers a driving experience that is still a benchmark today. However, it is no longer an ordinary used car: it is a 'youngtimer' that requires rigorous and preventive maintenance. The top choice is the 530i (M54) for its performance, or the 528i (M52) for its raw reliability. Avoid neglected or cheaply modified examples. Plan for an immediate budget of 1000 to 2000 € after purchase to ensure the reliability of the cooling system and suspension. If you accept these conditions, it is one of the best sedans ever built.
