What in the fuck? Are you serious? EVERYONE has heard of those things, and if they were as cheap to get stateside as you thought they were every riceboy faggot would think he's Paul Walker. Yeah, you can find an RB26 Skyline for dirt cheap on those Japanese "JDM BRO" Import sites because those cars had a power steering leak, the gov't over there deemed them unable to be driven, and have been sitting for 5-10+ years. At least that's what happens with the motors. You spend $9500 on the car, plus shipping (For an idea, my buddy had a '92 3000GT RHD Front Clip and rear end shipped over, IIRC it was near $1,000 shipped, and not even to his shop's doorstep.) You buy a Skyline, pay shipping per cubic foot, then pay for all the inspections it has to go through, and when it doesn't pass (which it likely won't because if my sources are correct R33's and most R34's dont have bumper supports) you'll have 120ish days to get it brought up to NTHA's specs.
Cliffs
-Unless the buster hits the mega millions, no Skyline
-Better off buying R35 GT-R
