Old SLK Alloy Wheels Problem (03 Plate)

[WildCards]

My mum has an 03 plate SLK which has developed the milky wheel syndrome (Laquer buggering up) on all four wheels, she's had a right problem with the dealership as she has kerb damage to each wheel. They are saying because of this the warranty is void, despite the laquer damage being in the centre of the wheel and the kerb damage to the outer rim.

I've contacted MBUK who are also standing behind this bogus excuse, can anyone shed any light on our next move other than writing to Daimler Chrysler.

Thanks
