I have a 2003 S500 and my dealer tells me that I need a full headlight assembly, instead of going through the dealer and paying $1200, I would like to buy cheaper elsewhere, but I'm not sure what I need. I do have factory installed xenon lights, any info you all can give would be appreciated!!

 

Only buy the oem from wherever you buy them. But yes, ebay is probably the easiest place to buy them, and the cheapest.

If you are in the US, try www.lkq.com. They are a large connection of wrecking yards.

 

yeah there are many cheaper hid kits attainable in the stores just search for it i have even heard for a 60 $ hid kits i do not have the address of the store but i am sure that it is present somewhere so go find out
