I don't think there will ever be the perfect one. They will all have sth that needs doing, for me it is part of the ownership and making the car yours. By the way, not sure if you remember when I bought mine, I was after a driver's dimming mirror as mine had a slight cloud in it, well I managed to buy one on ebay with its original mercedes box for £50. It seems new. Nobody bid on it, so I am still laughing, considering mercedes part portsmouth that sell such parts sold one a few weeks back for £119.
