I have a bit of experience with this because I also have a (completely legit) weird VIN on one of my cars. Unfortunately I don't have good news...

On 99% of cars they can scan the VIN and it automatically enters into the computer. They *can* enter it manually, although they might say they can't. But if they enter it manually then they're subject to additional scrutiny and audit from MTO. So they'll want to match the VIN on the ownership against the VIN on the car (red flag), take pictures of your VIN (red flag) and so on. At the end of the test an MTO guy might pop up on the screen and ask for additional info via Web cam.

You only hope is to find someone lazy that just enters the VIN without checking against the car, and the MTO guy is sleeping during your test.

I'd look into getting it fixed. I wonder if you can order a new door jamb sticker from Chrysler/Mitsu.
