hey ppl
for ppl in canada or us owners who did not get the HID option, you can use the stock halogen projectors and install a set of HID kit, but the output won't be as good as projectors made for HID lighting.
But if you are on a budget, shop around of HID kits (get osram (OEM) and phillips kits) probably on ebay would be a good starting place... if not check the classified section from
www.hidforum.com
BUT if you want to go all out, get some HID projectors and retrofit, but since the M3 is a new car... you probably won't want to fiddle around iwth anything hahahaha
