The BMW 3 SERIES (2005-12) 318I 129 4DR SALOON 2.0 AUTO is a compact executive saloon: a four-door, petrol-powered family car with a more premium feel than mainstream small saloons. In the UK used market, it sits among alternatives such as the Audi A4 and Mercedes-Benz C-Class, and is known for balanced, enjoyable driving. Automatic transmission makes it appealing for commuting and urban traffic, while the comfortable cabin and boot suit couples or small families needing practicality. It is less suited to buyers prioritising the lowest running costs: this older BMW may cost more to maintain than a simpler mainstream saloon, so condition and service history matter. mycarcheck.com has recorded seven checks across five VINs, a limited sample. Those records show an average private-sale value of £1,600, mileage of 110,000, and seven previous keepers; average annual mileage is 3,000. Treat these figures as a guide only, and check each car's history.
