My 05 325ci's bi-xenon with adaptive light cost $800.00.
It shouldn't cost $7000 for parts or whatnot.. they probably
want to put projectors on it when actually you can just get
D2S bulbs from an S2000 or RX-8 .. if you already have
Assumin you already have HID but want the more BLUISH look.
My 04 Mazda 3 had HID but it emitted a super white light and I
wasn't too happy with it so I asked around and turns out you can
just replace with a higher light temperature xenon bulb. So I bought
RX-8 bulbs. $170 each. Works fine. Better color.
