BMW 6 SERIES (2004-07)

Buyer's Guide & Data from our Checks
The BMW 6 SERIES (2004-07) is a large, premium two-door coupe or convertible, rather than a practical hatchback or family SUV. In the UK used-car market it sits among luxury grand tourers: cars designed to make longer journeys feel special, with comfort and presence as well as strong performance.
mycarcheck.com has recorded 11,396 look-ups across 3,484 different VINs, a substantial sample of buyer interest. Checks show an average private-sale valuation of £4,000 and average recorded mileage of 111,000 miles; typical annual use is relatively low at 5,000 miles. The average keeper count is about six, so check each car’s history and condition carefully.
With its shape, refined cabin and engaging drive, the 6 Series suits couples or enthusiasts wanting an occasion-making weekend car or comfortable long-distance companion, not buyers prioritising cheap running costs or rear-seat access. It offers an indulgent alternative to a Mercedes-Benz CLK or Jaguar XK, with BMW’s character.
