Its long-distance comfort and distinctive looks make it suited to couples or experienced drivers wanting something special, rather than a practical family car. mycarcheck.com records 1,756 look-ups covering 530 different VINs, a useful sample of buyer interest. Its observed average private-sale valuation is £3,300, with average recorded mileage of 122,000 and annual use around 6,000 miles. Cars checked had about six previous keepers on average, so condition and history deserve careful attention. Against CLK and XK rivals, this BMW blends sporty character with relaxed cruising.
