Yesterday, I was amazed to find out that at my 06-er Phaeton on the lower edges of both doors there are real rust bubbles in front of it. Strange, I thought so far, that aluminium does not rust. When I am back in the north, I will go to the friendly as well as the seller to have this deficiency eliminated. I am excited whether it takes many persuasion to convince one of the two that the removal of defects is either a guarantee or a guarantee. In my opinion, it is extremely embarrassing for the manufacturer that aluminium doors (allegedly?) can form such rust after five years. Finally, even with Fiat, Renault and some other manufacturers, the times should be long over even with sheet metal.
