The BMW 6 SERIES (2004-07) 645I 2DR COUPE 4.4 is a large, two-door luxury coupe, sitting above everyday BMW saloons as a stylish, high-powered grand tourer rather than a practical family hatchback. In mycarcheck.com records, this model has 94 look-ups covering 37 distinct VINs, giving a useful snapshot of used examples. The average private-sale valuation is £2,600, while recorded mileage averages 125,000 and annual mileage 4,000. Checks show an average of 6.2 previous keepers, so buyers should review each car’s history carefully and assess condition rather than rely on averages. With its long bonnet, sleek shape and V8 character, the 645i suits drivers seeking engaging journeys. It is best for couples or occasional passengers, rather than families needing rear-seat access or low running costs. Compared with the Mercedes-Benz CL and Jaguar XK, the BMW stands out for its grand-touring feel, but age and fuel use make careful checks and budgeting essential.
