# 2008-2015 BMW 730i The BMW 730i served as the entry-level variant of the F01/F02 7-Series, BMW's flagship luxury sedan. Powered by a 3.0-liter inline-six producing around 258 horsepower, it offered smooth performance and impressive fuel economy for its class, though it felt underpowered compared to its eight-cylinder siblings. Reviewers praised its refined ride quality, cutting-edge technology (including iDrive), and exceptional build quality, though criticized its complex electronics and steep depreciation. The 730i gained infamy for reliability issues, particularly with electronics, turbochargers, and the N52/N53 engine's timing chain and fuel injectors. Today, it suits buyers seeking affordable luxury sedan transportation who aren't intimidated by potentially expensive repairs. Best for those wanting 7-Series prestige without V8 running costs, though prospective owners should budget generously for maintenance.
The F01/F02 730i features BMW's N52 inline-six, more reliable than turbocharged variants but still expensive to maintain. Common issues include electronic failures (iDrive, parking sensors), air suspension problems ($2,000-3,000), and valve cover gasket leaks. Premium fuel required. Insurance costs are high. Parts and labor exceed mass-market brands significantly. Budget $2,000-4,000 annually for maintenance.
