BMW 5 Series 545e.
What to Check Before Buying.

The BMW 5 Series 545e is a plug-in hybrid executive saloon that suits company car drivers and high-mileage users seeking WLTP-certified electric range of around 35 miles alongside petrol performance when needed. This variant combines a 3.0-litre straight-six petrol engine with an electric motor, delivering impressive acceleration and low benefit-in-kind tax rates that made it attractive to business users. However, real-world electric range often falls short of official figures, particularly in cold weather or with heavy motorway use. When buying used, verify the charging cable is present and check the service history confirms battery health checks at BMW intervals. Test the transition between electric and petrol modes during your drive, as rough shifts can indicate worn engine mounts or hybrid system faults. Examine the underside for damage to the battery pack, especially on cars with urban use where speed bumps pose risks. Request evidence of software updates, as early cars sometimes experienced charging system glitches. The 545e offers executive comfort with tax efficiency, but only delivers value if the previous owner maintained it properly and charged regularly.
