It was all-change in 2003 for BMW and the 5 Series. With a bold new look, the new cars known by enthusiasts as the E60 and E61 – the latter being the estate version – also introduced a raft of new technologies, from the iDrive infotainment system to a range of driver assistance functions and more besides. There’ll be an engine to suit your particular needs and preferences, and as long as you can live with a busier ride quality, you could land yourself the best-handling saloon/estate of the day.
