FWIW:
Just spoke to Nic about ordering a set of headlights for my red 370Z. Getting the satin black internals with color-coded headlight and turn signal surrounds for $650, plus a fully refundable $700 core deposit. For LEDs (which I didn't order, as I feel this is an "Audi" thing), it's an extra $400. Note, the fee is for the housings only, so I have to move over all the headlight components from my car to the housings he sends me, then ship him my old housings.
I overnighted a money order for $650, and will be placing the deposit via credit card through Nic's bank (he says Paypal charges too high an interest rate...?). He says he'll get back to me within a day or two with details about the deposit as well as when I can expect the headlights here.
More info as I get it...feel free to chime in with questions or opinions on this topic or vendor...
Thanks.
