Alright. There's a couple of ways to do it and here's how. Most of the Police on the island of Montreal are stupid so it's pretty rare they would know anything about Skylines and how they are sorted in Quebec, you just need to worry about South Shore, North Shore.. pretty much the outskirts of Montreal and Quebec etc... So be careful who you talk to and post online because there's a lot of haters and jealous people so you could be one phone call away from getting arrested or your car seized but if you play your cards right & stay low key with your r34 you'll be fine. Trust me.
Okay so here go
1). Register the vehicle under a different province. I recommend Ontario, obviously. There's literally no way to get caught from this. It's the most legitimate way. Unless someone tries really hard to fuck you up by snitching and starting a Police investigation on you OR you live in a small town where Police will notice you a lot and get suspicious (Which is rare).
2). Register the vehicle under a Dealer Plate (X). It will cost you around $168.81 + Insurance and 100,000$ Bond in your bank account. In the end.. is that really worth it? I don't think so unless you really own a dealership. OR you can get someone you know to put it under their name that owns a dealership.
3). VIN Mixup. This is the most risky way. Switching the BNR34XXXXXX to BNR32XXXXXX. I only know one person in Quebec that has done this but it's insanely ballsy.
4). R32 to R34 conversion. It'll cost you about 14k for the work and parts so that's another way.
5). SAAQ Fraud. Register and editing import and licensing numbers. Can be done. However extremely risky.
6). Wait until 2024
