I don't have an owners manual and can't seem to find one anywhere. And a dash operating manual would be helpful. (This is my first Mercedes and I don't know what all the buttons and knobs do, or what they are supposed to do!) Also, any products available that can put the shine back in my chrome trim? This car is in great shape bet it sat outside and was forgoten for 5 or 6 years and the chrome is pretty dull! I have tried Turtle wax and a couple of differant polishes bet it is still pretty dull!
