# 2005-2008 BMW 750i The E65/E66-generation BMW 750i represented BMW's flagship sedan, powered by a naturally aspirated 4.8L V8 producing 360 horsepower. This luxury cruiser featured the controversial Chris Bangle design with flame surfacing and an divisive trunk line that polarized enthusiasts. Reviews praised its powerful engine, advanced technology including iDrive, and refined highway manners. However, it's infamous for complex electronics and expensive repairs—particularly the notoriously problematic valve stem seals and aging air suspension systems. The 750i garnered criticism for being over-engineered, with reliability concerns that significantly impact ownership costs. Today, it appeals to budget luxury buyers willing to tackle maintenance challenges or enthusiasts seeking depreciated German flagship performance. Best suited for those with mechanical knowledge or deep pockets for repairs, rather than daily driver duty without warranty protection.
