The MAZDA CX-3 (2015-18) 5DR SUV 2.0 SKYACTIV SS 120 EU6 SE AUTO6 is a compact, five-door crossover: taller and more rugged-looking than a hatchback, but easier to park than a larger family SUV. It offers a useful middle ground in the UK used-car market, with automatic convenience and a petrol engine. Mycarcheck.com has recorded 29 checks covering 15 different VINs, a useful snapshot rather than a full picture of every CX-3. Those checks show an average private-sale valuation of £9,000 and average recorded mileage of 42,000 miles; annual mileage averages 7,000, with about two previous keepers. Treat these figures as a guide, and check each car’s history and condition. With styling, a raised driving position and Mazda’s engaging road manners, it suits commuters, couples and small families wanting SUV practicality. Against rivals such as the Nissan Juke, it feels more grown-up, while its automatic gearbox makes traffic less tiring.
