The BMW 5-Series E39 (1996–2003) is widely regarded as one of BMW's most balanced executive cars, combining rear-wheel drive with a range of inline-six and V8 engines, including the 540i's 4.4L M62 V8 and the high-performance M5's 4.9L S62 V8. Its chassis uses a multi-link rear suspension, double-pivot front suspension, near 50:50 weight distribution, and hydraulic steering, giving the E39 a mechanical driving character that became less common in later generations.

The E39 has strong future-classic potential because of its combination of proportions, analog controls, naturally aspirated engines, manual transmission availability, and relatively straightforward chassis engineering. The M5, 540i, and manual-equipped six-cylinder models are particularly sought after, while the generation's reputation for handling, build quality, and BMW's traditional rear-wheel-drive layout has helped maintain interest among enthusiasts and collectors.
