/// Why this one
The E39 M5 is widely regarded as the high-water mark of the BMW M Division — the moment when sport sedan philosophy, engineering, and budget all peaked simultaneously.
Subtle to the point of invisibility. The only car in the collection that could plausibly be used as primary daily transportation.
/// Provenance
S62 V8: 4.9-liter, all-aluminum, double-VANOS, dual-throttle-body, 394 hp and 369 lb-ft. Getrag 420G six-speed manual was the only transmission ever offered, with no automatic option in any market. Production approximately 20,000 cars worldwide.
Risk note: VANOS units and Nikasil-bore early engines require verification; later production blocks with Alusil are preferred.
