Analysis

What Problems Does the 2008 BMW 6 Series Have?

Frequently reported problems for the 2008 BMW 6 Series often revolve around electrical components, including issues with the iDrive system, sensors, and wiring harnesses. Oil leaks, particularly from valve cover gaskets and the oil filter housing, are also common. The convertible top mechanism (on convertible models) can be prone to malfunctions, requiring costly repairs.
While specific recall information should be checked with the National Highway Traffic Safety Administration (NHTSA) database using the vehicle's VIN, common BMW recalls sometimes involve fuel pump issues or airbag system malfunctions.
Long-term reliability concerns include the degradation of rubber and plastic components due to age, leading to vacuum leaks and coolant leaks. The automatic transmission, while generally robust, may require servicing or replacement at higher mileages. It's crucial to maintain regular servicing to mitigate these potential issues. Pre-purchase inspections by a qualified BMW mechanic are highly recommended to assess the vehicle's condition and identify any existing or potential problems.

How long will the 2008 BMW 6 Series last?

With proper maintenance, a 2008 BMW 6 Series can provide 150,000 to 200,000 miles or more of service. However, longevity depends heavily on consistent maintenance habits, including regular oil changes, fluid flushes, and addressing minor repairs promptly. Owners who neglect maintenance can expect significantly shorter lifespans and increased repair costs. Long-term durability weaknesses include the aforementioned electrical issues, oil leaks, and suspension component wear. The interior trim may also show signs of wear and tear over time. Careful ownership and preventative maintenance are key to maximizing the vehicle's lifespan.

What Technology & Safety Features are Included?

The 2008 BMW 6 Series came equipped with a range of built-in tech, entertainment, driver-assistance, and safety features. The iDrive system, though initially criticized for its complexity, controlled many vehicle functions, including navigation, audio, and climate control. The standard audio system was high-quality, and a premium sound system upgrade was available.
Driver-assistance features included Dynamic Stability Control (DSC), anti-lock brakes (ABS), and parking sensors. Optional features included adaptive cruise control and lane departure warning. Safety features included front and side airbags, as well as active head restraints.
Crash-test ratings from the Insurance Institute for Highway Safety (IIHS) and the National Highway Traffic Safety Administration (NHTSA) should be consulted for specific scores, but generally, the 6 Series performed well in crash tests for its era, reflecting BMW's commitment to safety. Remember to verify the specific safety features equipped on a particular vehicle, as some were optional extras. The availability of features like adaptive headlights also enhanced safety during night driving. The advanced technology, even by today's standards, contributes to a refined driving experience.

2008 BMW 6 Series Insurance

Insurance for a 2008 BMW 6 Series is moderately priced, reflecting its status as a Coupe with strong safety ratings and
reasonable repair costs.

How Does the 2008 BMW 6 Series Compare to Other Coupe?

The 2008 BMW 6 Series competed with vehicles like the Mercedes-Benz CL-Class, Jaguar XK, and Audi A5 (later models). In terms of performance, the 650i's V8 engine was competitive, offering strong acceleration and a sporty driving experience. Feature-wise, it offered a comparable level of luxury and technology, although the iDrive system was often criticized for its complexity compared to Mercedes' COMAND system.
Reliability is where the 6 Series tends to fall short compared to some rivals. The Jaguar XK, while offering similar levels of performance and luxury, can also suffer from reliability issues. The Mercedes-Benz CL-Class, while more expensive to maintain, is generally considered more reliable. The Audi A5 (while smaller) offers a more modern and reliable alternative at a lower price point on the used market.
Similar alternatives in terms of style and performance include the Lexus SC430 (known for its reliability) and the Porsche 911 (for a sportier, albeit less luxurious, experience). If reliability and lower running costs are priorities, consider the Audi A5 or Lexus SC430; otherwise, the 6 Series remains a compelling choice for those seeking a blend of performance and luxury at a used car price.

The 2008 BMW 6 Series 650i is ideal for enthusiasts who appreciate a blend of performance and luxury, and who are willing to accept higher running costs. It's a worthy buy on the used market *if* a thorough pre-purchase inspection is conducted by a qualified BMW mechanic. Opt for well-maintained examples with comprehensive service records. Be prepared for potentially expensive repairs. The coupe offers a sportier driving experience, while the convertible provides open-air thrills. It's not recommended for those seeking a budget-friendly or ultra-reliable vehicle. However, for the right buyer, it offers a rewarding ownership experience.
