Lived 6 doors from the Old Barge.
You will have problems with the 63 as I have with 43, there are no all weathers available. I took MB to the ombudsman and they eventually gave me a set of 20 inch wheels with winter tyres, as far as I am aware nobody else has been given new wheels. Apparently the new "fix" of steering arms/knuckles isn't applicable to the 43 and I would assume the 63. Keep browbeating your dealer and customer services, it is a disgrace that they are still producing cars with a fault that has been known about for nearly 2 years.
Let us know how you get on.
