BMW X6 (E71)
The original X6 (E71) essentially invented the coupe-SUV segment, combining the heavy underpinnings of the E70 X5 with a dramatically sloping roofline. Positioned as an aggressive, style-led alternative to traditional SUVs, it polarized opinions but sold surprisingly well to buyers wanting maximum road presence. Because it is based on the E70, it shares all of its expensive faults, meaning EPB failures, leaky panoramic roofs, and diesel timing chain issues are very common. It suits buyers who prioritize bold styling over practicality and are prepared for high maintenance bills.
