    An over-enthusiastic valet pressure washer has stripped off small (3-inch) patches of lacquer under each of the windows.

  3. Reserve Fuel

    Does anyone know how much reserve fuel a 451 holds and does it only go onto the reserve when there is less than one fuel bar remaining?

  4. V11 Brabus Alloys - Corrosion Enquiry

    Hi These V11 Brabus alloys come with 2 year guarantee but really doubt they would last this long and not show corrosion. Has anyone got the V11 silver alloys - any reports on corrosion versus how long you had the wheels. Thanks Simon

  19. Brabus tyres?

    Does anyone have any other preference to the standard Yokohama tyres on the rear of a 451 brabus. The size of 225/35/17 seems rather unpopular and therefore not much choice. Thanks in advance
