Nothing has gone wrong on mine, I have flaking wheels which will be sorted out.If you think of it logically the amount of development that went into the 400 was obviously good for the 430..It was after all its successor, there are merits in both cars I'm satisfied with mine as it sounds like most of you are.Both really good cars, when I bought mine the guy said smart people who know about cars buy a Lexus, the rest buy Mercs and Beemers.Its so nice to be affiliated with smart folk.
