  • BMW 4 Series (2020 on)
    Most affordable 420i is possibly the best 4 Series on sale. Incredible to drive. Superb interior. Feels more special than a 3 Series.
  • BMW 4 Series (2013 - 2020)
    Handles as impressively as you’d hope, handsome styling makes the newer 4 Series look fussy, wide range of strong petrol and diesel engines, plenty on the used market.
