About the BMW M6 E64

The BMW M6 Convertible (E64, 2006–2010) is the open-top counterpart to the E63, offering the same Formula 1-derived 5.0L S85 V10 engine but with an unlimited-headroom exhaust note. In the 2026 Australian market, the E64 occupies a distinct niche; while the Coupe is often preferred by purists for its stiffer chassis and carbon roof, the Convertible attracts a lifestyle-oriented buyer pool that views it as the ultimate "symphonic" cruiser. Desirability for the E64 is heavily dictated by the condition of its complex triple-layered soft top and the functionality of the vertical glass rear window, which acts as a wind deflector. Because the convertible is significantly heavier (2,005kg) than the coupe, it is rarely sought after as a track tool, which has paradoxically helped its 2026 survival rate, as fewer examples have been pushed to their mechanical limits. Market values in Australia generally sit slightly lower than the equivalent Coupe, typically ranging from $45,000 to $65,000 AUD, as the buyer pool remains wary of the additional maintenance required for the roof hydraulics and seals. To secure a resale premium, an E64 must demonstrate a rigorous service history focusing on the SMG III pump, rod bearings, and throttle actuators, alongside a "dry" interior free from the common water-ingress issues that plague the E64’s boot-mounted electronics.
