The BMW 7 Series E65/E66 generation, produced from 2001 to 2008, marked a significant departure for BMW's flagship sedan. It was the first 7 Series designed under Chris Bangle, introducing a controversial 'flame surfacing' design language and the revolutionary iDrive infotainment system. The E65 refers to the standard wheelbase, while the E66 denotes the long-wheelbase (Li) version. This generation was a technological showcase, featuring advanced electronics, active suspension (Dynamic Drive), and a range of powerful engines. While praised for its driving dynamics and luxury, its complex electronics and the initial learning curve of iDrive were points of contention. Its reliability, particularly concerning the V8 petrol engines and the intricate electronic systems, has been a frequent topi

The N52 (730i facelift) offers a good balance but has its own known issues (electric water pump, lifters). * For the best
