Wish I could give no star. We got stranded in France following a burst tyre. Mercedes needed to order a new tyre - that was all that was required. 6 days later I am still waiting on Mercedes to confirm if they have ordered the tyre - which they said could be 2-5 days. So poor, they are awful. I have no idea why Mercedes even offer roadside cover when it is so awful - lesson learnt I will now get decent cover from the AA or similar
