The BMW 7 Series E65/E66, launched in 2001, marked a bold stylistic and technological departure for the Bavarian brand. Designed by Chris Bangle, its controversial design divided opinion, but it introduced major innovations such as the iDrive infotainment system, the 6-speed automatic gearbox with a steering wheel-mounted shifter, and advanced chassis technologies. The E66 version is the long-wheelbase (Li) variant. Despite its luxury and performance, the complexity of its electronic and mechanical systems has often been a source of headaches for owners and workshops. A facelift (LCI) in 2005 brought aesthetic revisions and technical improvements, including new engines and an improved version of iDrive.

The BMW 7 Series E65/E66 is a fascinating luxury car, offering an impressive level of comfort and technology for its age. However, it is also one of the most complex and potentially expensive BMWs to maintain. For a confident purchase: Prioritize the 730i/Li (M54 or N52) or 730d/Ld (M57) engines. They are the least problematic and most affordable in terms of maintenance. A complete service history and a thorough inspection by a BMW specialist are imperative. For informed enthusiasts: The N62 V8s offer superb performance and sound, but anticipate a substantial budget for repairs (valve stem seals, coolant pipe). The N73 V12 is reserved for collectors or those with unlimited budgets, as costs can be stratospheric. In summary: This is a car that can offer a lot of pleasure for a negligible purchase price, but it requires an informed owner, a substantial maintenance budget, and, ideally, a good independent BMW-specialized mechanic. Don't be swayed solely by the low purchase price; the cost of ownership is that of a new luxury car.
