I have noticed that saleen had a speculated price of $1000 per kit. That seems very high for head lights, I am not sure exactly how specific HID kits are for individual cars, but it might be worth someones time to check out the group buy on mazda6club.com for HID headlights. They claim to have all available applications for cars, including dual filament H4 bulbs which I believe is on the new mustang. I am not on their forum so I don't know the requirements on the group buy since I stumbled on the name of the manufacture on a ebay auction. The manufacture is McCulloch (think I spelled it right) and they ship dirctley from Hong Kong. Once again I don't know if this will indeed work on the mustang, but if it does it is WAY cheaper than the supposed saleen price.
