Okay, So say I want one of these bad boys.

Yes, I know it's not 25 years. Yes, I know it's illegal. But say, I buy one of these from Canada, and drive it down to NJ. What are my chances of getting kicked out of the car while I'm at the border? I mean, I wont carry anything illegal into the car, and it's not like they're gonna ask me for my license and registration right? I mean, I'm just going to show them my passport and continue on my way as if nothing happened. I promise that I will drive within the speedlimit to avoid attracting attention.
