The MERCEDES-BENZ GL CLASS (2009-13) GL450 5DR SUV 4.0 CDI 306 SPORTS PACK 7G-T AUTO is a large, seven-seat luxury SUV, designed for buyers who need generous passenger and luggage space with a more imposing presence than a typical family crossover. In the UK used-car market, it sits above mainstream SUVs, competing with the BMW X5, Audi Q7 and Range Rover. Mycarcheck.com checks recorded 70 look-ups covering 26 distinct VINs, a useful snapshot rather than a complete market survey. Across those checks, average private-sale valuation was £12,100, while average recorded mileage was 123,000 miles. Average annual use was 8,000 miles, and cars had about 3.8 previous keepers. Best suited to larger families and long-distance travellers, it offers a comfortable drive, seven-seat flexibility and premium feel. Its size and running costs may not suit city use or tight budgets, but the GL450 is a spacious, luxurious alternative to common premium SUVs.
