Full review: http://www.autoexpress.co.uk/carreviews/firstdrives/253075/mercedes_sls_amg.html <br /> <br />Mercedes SLS AMG timed lap - Auto Express Performance Car of the Year <br /> <br />Building a supercar from scratch isn't easy, but Mercedes's in-house tuning arm, AMG, has an ace up its sleeve. <br /> <br />As with the original 300 SL, which wowed the motoring world 55 years ago, the doors are hinged at the top and sweep dramatically upwards -- the Gullwing is back and it's landed in the UK.
