ok heres a few of my opinions
I used to import parts, cars and stuff over here up until last year I still deal in some things like HIDs and the like
it is a good idea, but you must realize the market for such parts is just a tiny portion of the whole collison replacement part industry
to make new parts, your costs just go insane- to be honest certi-fit amazes me. My friend just picked up a front and rear bumper for his Maxima a few weeks ago for 25 bucks each I just cant believe they can make profit off of that
the market for this stuff may be bigger than just the used parts coming out of Japan, but its not big enough to set up factories to make OEM quality metal replacement parts... that niche is filled by fiberglass parts from companies like GTP International (impoertfan.com)
with the importation- tariffs are kind of high, but the biggest problem we started running into was that aftetr Sept 11th our containers could wind up sitting in customs for 3 monthes for no good reasons... we either had to have a huge inventory to supply people while our containers were stuck in customs... or we keep them waiting for 3 monthes... didnt have the inventory to do that didnt have the money to invest so much in wharehouses and overstock items like crazy... sooooo... we just called it quits
I've heard customs has changed alot, but I just had enough of it... its been a huge pain in the butt
