Apple MacBook Air i5 1.7 13.3inch 4GB 256GB SSD 2011 model ?

Bought in July 2011 the Macbook air comes with original charger and box. The machine has been thoroughly cleaned inside and out and comes with a fresh install of the OSX Mountain Lion. The Macbook Air functions perfectly and has no dead pixels, battery is also in good health and I easily get 4-5+hr of browsing on it. Comes with sleeve. I will only deliver to the UK, collections are welcome.
