What does the warning mean?

I doubt it. Vin plates are visible on every car since like '71. It's easy to look in a window and get a VIN, and no state will issue a title on just possession of a VIN.

If you can do it, tell me how. There's a 6.4 Challenger down the street.
Think about this when we go to Secretary of State we go with just paperwork and no car. So use your printer and photoshop to make a fake title in the owners name that you got from the internet with the VIN. Now pay them to transfer the fake title into your name. Say you also live in another state far away. Go steal the car and bring it home and hide it in the garage as long as you want but it is now yours. Oh you say what if you get pulled over trailering it home just show the cop your new legit title.
