# 2001-2008 BMW 730i The BMW 730i represented the entry point to the E65/E66 7 Series generation, featuring a 3.0-liter inline-six engine producing around 230 horsepower. This flagship sedan introduced controversial styling by Chris Bangle and the complex iDrive infotainment system—both initially polarizing elements that became infamous among enthusiasts. Reviewers praised its refined driving dynamics, comfortable ride, and luxurious interior, though many criticized the overwhelming technology and questionable reliability of electronic systems. The iDrive's early iterations were particularly maligned for their steep learning curve. Today, the 730i appeals to budget-conscious buyers seeking prestigious German luxury at depreciated prices. It's suitable for those comfortable with potential maintenance costs and complexity. The straight-six engine is generally more reliable than V8 alternatives, making it the sensible choice for experiencing flagship BMW luxury without breaking the bank.
The 2001-2008 BMW 730i (E65/E66) is notorious for expensive repairs, particularly the complex iDrive electronics, air suspension failures, and valve stem seal issues causing oil consumption. Expect high maintenance costs for sensors, bushings, and transmission problems. Parts and specialist labor are premium-priced. Insurance runs high due to luxury classification and expensive replacement costs.
