# 2006-2010 BMW X3 3.0si The first-generation X3 3.0si represents BMW's initial foray into the compact luxury SUV segment. Powered by a silky 260-hp inline-six engine, it delivers the brand's signature driving dynamics with responsive handling unusual for an SUV of its era. Reviewers praise its engaging road manners and powerful engine but criticize its firm ride, cramped rear seat, and spartan interior compared to competitors. The X3 became infamous for its harsh suspension tuning and polarizing styling. Today, it suits driving enthusiasts seeking an affordable entry into BMW ownership who prioritize performance over comfort. Reliability concerns, particularly with electronics and cooling systems, make thorough pre-purchase inspections essential. Best for singles or couples wanting a practical daily driver with sporting character, though modern alternatives offer superior refinement and technology.
The 2006-2010 BMW X3 3.0si requires premium fuel and expensive synthetic oil changes. Common issues include transfer case failures ($2,000-4,000), valve cover gasket leaks, and cooling system problems. Parts and labor costs are significantly higher than non-luxury competitors. Reliability is below average for the class, though less problematic than larger BMW SUVs.
