back when I was looking into importing Gwagens/70 series, seems that you could import any year vehicle if you claimed it to be off road only, like farm use only and you can't drive it on the road or register it. Don't know if I remember this correctly since it's been a while.
Any idea on how to get info on this?
There is no Federal exemption for "off road only". The closest thing would be box 8 on the US DOT NHTSA form HS-7, which is the form you use to declare your vehicle's eligibility for import. If you select box 8, you're declaring that: "The vehicle was not manufactured primarily for use on the public roads and thus is not a motor vehicle subject to the Federal Motor Vehicle Safety, Bumper, and Theft Prevention Standards".
Which, strictly speaking, isn't true--the vehicle
was manufactured for use on public roads, you're just not planning on using it that way. What we'd all
like box 8 to say is "we don't intend to use it on public roads". But it doesn't say that. And if you declare that (i.e. check box 8), you've perjured yourself. Federal crime. Bad idea.
If you are going to try use the grj model with the 4 runner engine that can be made to pass emissions.
Anything newer than 25 years old needs to be imported through a Registered Importer. If you contact one, they can walk you through the process, but the simple version is that they would need to petition the US government to allow the vehicle to be imported, and the US government would need to assent. There are two hurdles: EPA and NHTSA. Yes, the grj model with the 4Runner engine would be much easier to get past the EPA--all the parts are available to make the motor EPA compliant, so that shouldn't pose a problem. NHTSA is a bit more of a concern. You may not be able to find a model with airbags, side-impact protection, crash absorbing bumpers, etc., etc. The vehicle would need to comply (or be modified to comply) with all relevant FMVSS as of the date of its manufacture. If you can find such a vehicle, you might be able to get it done, but I don't know of any market where Toyota built the 70-series with those features. OTOH, if you're successful, that model will be added to the list of vehicles we can all import. So you'd be a hero.
Find a good 75 Series and never look back.
Far and away the easiest solution.
