They have given me a like for like replacement in the meantime till mine gets fixed. The courtesy car has the exact same spec as mine, white saloon with black rims. It is the car they use for their AMG open days in Milton Keynes so it's prob been rinsed.
Not heard anything about my car yet, they are still waiting for a few parts to come from Germany.
Yeah I've got my eye on the E63 s line 4 matic, mercedes have told me it should be out in the UK perhaps in spring next year.
