Unfortunately, too many people like the OP simply surf the net until they find one person who says that they can do it for them, and then they move straight away into making mistakes. It's almost like denial - if people spent as much time reading the import laws as they do surfing the web looking for some anonymous forum poster to tell them it's legal, they'd understand a lot. You can see them get the straight dope from experts, with attached links and supporting data, and move on to talk about the loophole they heard about.
As far as downtime, most tuned cars are off the road most of the time. I wouldn't consider the web stories that you read about tuner R34s sitting under the knife or broken all the time representative of the build or quality of the car. I think it reflects more on what's been done and that there are a significant number of tuners that don't really know what they are doing. I can tell you that the R34 GTR is a superb car when it hasn't been messed up. Most in the states have.
And by the way - If you think being a Motorex owner is fun, imagine being told by every single person you've ever met that you overpaid and in Japan, they issue free Skyline GTRs to school children and they can be purchased, in mint condition, with no miles, and free lifetime gas cards for $50. Don't forget, their neighbors here in the USA, on either side of them, own one (each making over 1000HP), and their uncle just legally imported an R34 and is giving them their R33 because they are bored with it (after being tuned to 1200HP). Their friend in the Army will be putting several Skyline GTRs in their backpacks and bringing them home. Furthermore, R34 GTRs are like Mustangs, in Japan -- you can't walk 50 feet without seeing one.
In reality, they are damn expensive and relatively low production -- more blue Mustangs were made in 2006 than the entire run of R34 GTRs over four years.
With a little over 11,000 R34 GTRs in the entire world, some totaled, and many exported around the world, I hope you all have cars left to import by the 15 year mark in Canada or 25 here in the USA. But I have a bad feeling about that. Just watching the auctions you can see that R34 GTR prices are on the rise -- especially for very original cars.
