Audi RS6 saloon (2008): first pictures

By Ben Whitworth First Official Pictures 12 August 2008 00:01 Following on from the RS6 Avant launched at the start of the 2008, Audi has revealed the saloon version of its hottest A6. And it’s hot!

2013 Land Rover Defender gets a bit more appealing

Land Rover has updated the Defender for 2013 with new colours, new premium seat design and upgraded in-car entertainment.

Land Rover has decided to offer a new range of contrast roof colours for the Defender, with the normal white option being extended to include Santorini Black, Indus Silver, Orkney Grey or Firenze Red and available on almost the whole of the Defender’s paint jobs.
