Motorex can still legalize Imports to the US. I really want this car and i'm very willing but if i could get the car for $20,000 less, by any means necessary, i'll do it.
My importer has an R34 (in Korea now) that you might swing for $30,000 or so. It's missing an engine and transmission, but has a complete interior. You *may* be able to bring it in as a "rolling assemblage of parts", but then again, you might not, and it could get seized by US Customs. Skylines are a bad word for the US DOT currently with the whole Motorex debacle and a highly recognizable car. Legalization costs for an R33 (modifying the car to come into NHTSA and DOT compliance) will cost $20-$25,000 on top of the car's price, if you can find someone who'd do it.
Motorex is out of business and already liquidated, and the cops are still trying to track down some of the cars that were stolen from customers. Only airbag-equipped R33 Skylines that do not have OBD-II engine management ('95-'96)can be legalized, but no one's been able to do it yet.
Your only option to get a legal R34 is to buy one that Motorex has already managed to sneak in and get legalized (as 1996 model year cars, part of the reason why they got shut down), and is already in the US. Expect to pay six figures. Otherwise, get an R34 in Japan, disassemble it down to a shell and several crates of parts, ship it to America all to different locations, then reassemble it and hope a federal agency never sees your car on the road. Or, go to Japan, marry a Japanese woman, register the car in her name, and she can bring in the car under a personal exemption. But the car must be exported or destroyed after one calendar year. Or, buy an R34 Z-tune, which might make the Show and Display exemption (under which the Porsche 959 was finally made legal).
