hows it going everybody?i got an 01 clk430 convertible. i want to get xenon lights in there. presently it has stock halogen lights. i believe h7 bulbs. there are so many companies out there and i just would like to know from someone's personal experience which is the way to go. also need to get a gps put in. my car doesnt have it. should i get a used factory gps/radio or go aftermarket and get like a pioneer/alpine/kenwood unit?
