So, I'm going to do a halogen to HID retrofit on a pre-facelift 03. I found a guy that will sell his used OEM enclosures and bulbs for 150. They are in normal condition for a 03 set of lens and only include the enclosure and bulbs. Is 150 a decent asking price? I realize the balasts, etc are going to cost me additional, but I need a starting point and I'm thinking this is probably a decent price???
