The BMW 7 Series E65/E66, launched in 2001, marked a bold stylistic and technological break for the Bavarian brand. Its controversial design, the work of Chris Bangle, divided opinions, but it introduced major innovations such as the iDrive infotainment system, the 6-speed automatic gearbox (a world first), and advanced chassis technologies. The E66 version is the long-wheelbase (Li) variant. Positioned as the flagship of the BMW range, it aimed to offer cutting-edge luxury and technology, directly rivalling the Mercedes S-Class. Despite its dynamic qualities and comfort, its electronic complexity and certain reliability issues, particularly with the V8 and V12 petrol engines, tarnished its reputation. The 2005 facelift (LCI) softened the lines and improved some technical aspects. Overall

Buying advice: * Prioritize diesel engines (M57), especially the 730d, which offers the best compromise between performance, consumption, and reliability. It is by far the most reasonable choice. * Avoid V8 and V12 petrol engines unless you have an unlimited budget for maintenance and are prepared to face very costly repairs (valve stem seals, oil leaks, electronics). * Imperatively look for a model with a complete and clear service history, ideally performed at BMW or a recognized specialist. * Have a thorough pre-purchase inspection carried out by a BMW specialist, including a full electronic diagnostic. * Plan for a substantial annual budget for routine maintenance and unforeseen events (several thousand euros per year are not uncommon).
