BMW 7 Series (E65/E66)
The E65 7 Series was a radical departure for BMW, introducing the highly controversial Bangle styling and the very first, deeply complex iteration of the iDrive system. Positioned as a technological flagship, it was packed with heavy, early-2000s electronics that have not aged well. In the UK used market, it is practically a disposable luxury car due to the sheer cost of repairing its failing control modules, fragile V8 engines, and active suspension. It is strictly for brave mechanics wanting a massive luxury barge for pennies, though keeping it on the road will test their patience.
