The BMW 3 Series Saloon is a premium compact executive car, offering a smart four-door alternative to family hatchbacks. This 2011–15 320i combines a 2.0-litre petrol engine and six-speed manual gearbox with SE Business Media trim. It competes with the Audi A4 and Mercedes-Benz C-Class, balancing comfort with an engaging drive. With four doors and a comfortable cabin, it suits commuters, couples and small families wanting a more refined daily car, as well as longer-distance drivers. The 184PS petrol model offers brisk, smooth performance, while stop-start technology and Euro 6 compliance are useful considerations for everyday running and emissions rules. It feels more involving than many mainstream family saloons. mycarcheck.com recorded 29 checks covering 10 distinct VINs, so figures are indicative rather than a full-market survey.
