The BMW 5 SERIES (2007-10) 523I 4DR SALOON 2.5 190 M SPORT is a spacious four-door executive saloon, aimed at buyers wanting more comfort and presence than a family car. In the UK used market, it sits among alternatives such as the Audi A6 and Mercedes-Benz E-Class, with BMW’s sporty image. The 2.5-litre petrol engine and M Sport styling give this 523i a more engaging character than a basic saloon, while its roomy cabin and boot make it suitable for commuting, business travel and family trips. Mycarcheck.com recorded 55 look-ups across 23 VINs, giving a snapshot of cars being researched.
