A180 AMG Line Premium Plus Auto with Distronic (the one bit I wanted!)
Did a good run yesterday (80 miles) just to charge the battery and bought a Ctek and gave it four hours on that. Reading 12.6v at that point (up from 11.7). Never been sure whether I was playing around with buttons which was causing previous battery warnings so I am avoiding that and checkeing daily now. In 24hrs dropped to 12.3v.
