The MERCEDES-BENZ GL CLASS is a large, premium SUV, sitting near the top of the UK market for spacious family 4x4s. With imposing styling and room for up to seven, it offers a more substantial, luxurious feel than many everyday SUVs. It is now mainly found as a used purchase. Mycarcheck.com has recorded 3,660 look-ups covering 1,326 different VINs, giving a useful snapshot of used-car interest. Checks show an average private-sale value of £21,000 and average recorded mileage of 91,000 miles; typical annual mileage is 8,000, with around three previous keepers. These figures describe vehicles checked, not every GL CLASS. The GL suits families, long-distance travellers and drivers who want comfort, a commanding view and passenger space. Its plush cabin and relaxed road manners set it apart from sporting BMW X5s, while it competes with the Audi Q7 and Range Rover. Expect higher fuel and upkeep costs than smaller SUV.
