EPA certification... the cars pass CARB requirements and EPA, but since it's not a car intended for sale on us soil, the EPA does not intend on keeping records of this model of car. \
So here's the bad part.....You have to get each one individually EPA certified. Which means it has to go through their tests....and certs cost loads. THe parts are cheap, but the cert is prolly 15k+ of it easy. Its somehting around 30k to get a skyline EPA certified (according to j-garage, another skyline importer). SOme importers (j-garage) just sell you the car, you have to do the customs work, EPA cert, etc yourself. Those guys can get you a 93 gt-r for about 15k, but after certs and tariffs itl be more like 45k. my guess is motorex tacks about 10k on top, which considering hte rarity of this car within hte us, is a small price to pay for a car like that.
Just to give you the idea of how bad certs are, take my job...we had to UL cert a modem......2500 dollars a day.....a day! It took 3 days and 20 modems to get a UL certification. so for a 80 dollar modem we threw 7500 dollars in cert fees alone, then another 1600 in hardware costs.
Motorex wasnt for the guy who doesnt want to deal with things, just wants his skyline, if you don't mind doing hte details, just go to the smaller importers anyways the small guys usually bring other cars in too, like evo 4's and stuff
