Reliability snapshot
The E63/E64 6 Series is a grand tourer sharing much of its mechanicals with the E60 5 Series. Common items therefore mirror that car: the N62 V8's valve-stem seals and coolant transfer pipe, early iDrive/electronics faults, and general cooling-system wear. The M6 variant uses the high-strung S85 V10, which has its own specialist maintenance needs. Regular cooling maintenance and attention to the V8 wear points keep the E63 healthy.
