The BMW 523 has been a staple of the 5 Series family for multiple generations. A 2.5-litre petrol engine variant, it's no longer in production. However, during its time, it received consistent praise for its robust build, high-quality interior and calm, capable drive, which suited families and professionals alike. Across all generations, you’ll find standards like ample room in both the front and back, a smooth engine and advanced levels of technology. Not to mention a decent-sized boot. Next to rivals like the Mercedes E-Class and Audi A6, the BMW 523 is class-leading, offering a truly comfortable drive and a refined look and feel.
