# 2005-2008 BMW 730Ld The BMW 730Ld represents the diesel flagship of the E65/E66 7 Series generation, powered by a 3.0-liter twin-turbo inline-six producing around 230 horsepower. This long-wheelbase variant offered exceptional rear-seat space and surprising fuel efficiency for a luxury limousine. Reviewers praised its refined diesel engine, impressive torque delivery, and comfortable ride, though the polarizing Chris Bangle design and iDrive system complexity drew criticism. The model became infamous for expensive electrical gremlins and air suspension failures. Today, it's well-suited for budget-conscious buyers seeking BMW's flagship luxury experience, particularly chauffeur services or those prioritizing rear-seat comfort. The diesel engine offers economy on long motorway journeys. **Ideal for:** Value-oriented luxury seekers, executive transport services, European markets where diesel parts availability remains strong. Prospective buyers should budget significantly for maintenance and seek examples with comprehensive service histories.

Turbos may need replacement around 150k miles. Parts and labor costs are premium-tier. However, diesel fuel economy partially offsets costs. Specialized BMW servicing required; independent mechanics can reduce expenses significantly.
