BMW introduced the X6 for the 2008 model year, creating a new niche it called the Sports Activity Coupe. Based on the X5, the X6 (E71) combined a high-riding chassis with a controversial fastback roofline. Engine choices ranged from a turbocharged inline-6 in the xDrive35i to a potent 4.4-liter twin-turbo V8 in the xDrive50i, with the 547 horsepower X6 M arriving in 2010.
The X6 is significant for pioneering the coupe-SUV segment that many other luxury brands later copied. First-generation models, particularly the X6 M, are gaining interest for their bold design and impressive performance. While not a traditional collector car, its unique place in BMW's history and the performance of M variants make it a compelling modern classic.
The market for the X6 is very broad, covering three generations. Early, high-mileage V8 models are now quite affordable, but they come with significant maintenance risks. The average transaction price of around $26,000 typically buys a second-generation (F16) model from the mid-2010s, while the newest G06 generation models command the highest prices.
Buying Tips
- Beware of early N63 V8 engines in xDrive50i models. They are known for high oil consumption, leaking valve stem seals, and timing chain problems. Look for proof of the BMW 'Customer Care Package' service campaign.
- The N54 and N55 inline-6 engines are more reliable but still require checks. Listen for wastegate rattle on the N54 and inspect for common oil leaks from the valve cover and oil filter housing gaskets on both.
- These are heavy vehicles that are tough on suspension and brakes. Listen for clunks from worn control arms and check for uneven tire wear. Brake jobs, especially on M models, are expensive.
- Test all electronics thoroughly. The iDrive system, power tailgate, and various control modules can fail and lead to costly repairs. A pre-purchase inspection with a BMW-specific scan tool is a good idea.
- Check for transfer case issues on all xDrive models. A stuttering or binding sensation during slow, tight turns can indicate a worn-out transfer case, which is a very expensive fix.
Prices range from $2,148 for early, high-mileage examples to $77,500 for recent, high-performance variants.
