The MERCEDES-BENZ E CLASS (2002-06) E320 5DR ESTATE 3.2 CDI AVANTGARDE AUTO is a large, premium diesel estate: a practical alternative to an executive saloon, with space for family life, holidays and bulky loads. In the UK used-car market it sits above mainstream estates such as the Ford Mondeo, offering a more luxurious feel and strong motorway comfort. Mycarcheck.com has recorded 702 look-ups covering 342 different VINs, giving a useful sample of interest. Checks show an average private-sale valuation of £1,600 and average recorded mileage of 160,000 miles; typical annual mileage is 8,000. The cars checked had about 4.6 previous keepers on average, so condition and service history matter more than the badge. Comfortable and spacious, it suits families and motorway commuters needing comfort, space and an automatic. Avantgarde trim feels upmarket, and the E-Class estate is prized for refinement against rivals, though age-related upkeep can be costly for class.
