Happy to help.
So it started like this. At one point, his car had been shipped to florida (which was the only real entry point into the US as far as seaports) at which point, the process was begun to title it as a kit car. But the dealer that did it was a moron, and gave up about halfway through. He instead had the car trucked to CA, where he "got a title" (read didn't do squat, because CA had put the screws to all grey market folks) and drove it around as his personal vehicle. At some point, he moved to MN, where his intention was to title it under MN kit car laws, which would give plates to a skateboard and some flashlights. In the meantime, MN regs changed to be more in line with the rest of the country in regards to legal importation of a vehicle. You can still do it legally, but you have to provide crash test results, change all the other equipement (crash bars and whatnot) and get em smogged before they'll cut you a legit title. The kit car option is all but gone. If you do it, it's possible, but you basically have to prove you bought every single part on the car through a legitimate importer (no more grey market half-cuts) who in turn had legally imported the parts through the US and brought them through customs. A lot of it has to do with clean air regs, and people "defeating" Emissions by swapping motors and claiming either pre-emissions or gray market. As I said in my previous post, it's taken him a good 7-8 months to get this all done, and as of right now, while the car does have plates and is insured, it's technically a Subaru Legacy, at least until it clears the last inspection. Your best hope is the 25 year rule at this point. I've been looking into the same thing myself, because there's piles of cheap R32 skylines in Canada, but I can't even legally bring the things across the border anymore. I'd have to hire a Canadian dude to drive it across, have him sell it to me in Seattle, get temp plates, and pray to god I didn't get pulled in Montana.
