The MERCEDES-BENZ GL CLASS (2012-16) is a large, premium seven-seat SUV, sitting near the top of the UK family-car market. It combines imposing road presence with room for passengers and luggage, making it a more luxurious, larger alternative to mainstream SUVs and a direct rival to the Audi Q7 and Land Rover Discovery. mycarcheck.com records 2,704 look-ups covering 974 distinct VINs, a useful sample of UK interest. Across checked examples, the average private-sale valuation is £24,500, while recorded mileage averages 81,000 miles; annual mileage is around 8,000. An average of 2.4 previous keepers means it is wise to check each car’s history and condition, as use will vary. This GL is best suited to families needing seven seats, or drivers who travel far and value comfort. Its roomy cabin, comfort and commanding view set it apart, but its size and premium running costs may not suit urban or budget-conscious buyers.
