It sits at the sporting, premium end of the UK used-car market, rather than competing with family convertibles or practical hatchbacks. mycarcheck.com records 3,011 checks covering 744 different VINs, a sample for this specific M3. Those checks show an average private-sale valuation of £14,200 and average recorded mileage of 72,000 miles; annual mileage averages 3,000.
