Reviewed a 2018 BMW 6 Series on 28 Jun 2026
Fabulous Driving Machine. All over Europe in it; become blase about the admiring looks, especially with the roof down. Sporty; no slouch. A diesel with 2 turbos; wow !!! And - to cap it all - several young ladies asking if they could be photographed in it. !!

Reviewed a 2018 BMW 6 Series on 29 Aug 2021
The hybrid version which BMW in my view erroneously have decided to sell in Europe but not the Uk would have been the ideal replacement for my 5GT. It looks as if I will have to look at the Audi or Merc ranges . A pity has I and my family, plus the company , have been almost exclusively BMW purchasers for well over 20 years
