Help... Vin #'s dont match

Authorities. What a joke. They will wonder where all the rest of the numbers are and why the vin # is so short.
Go ahead and take your stick and stir it up so everybody has to smell.
All they will do is take your money. It all they care about. Just walk right in there and explain to them how to screw you out of your car investment and what was supposed to be fun for you.
Sure they will continue to tell you its your wellbeing they care about and they will do so as long as you are fool enough to listen and pay.
See how much time they care to invest on behalf of you and your old car when they find no one to pay.
Best advice. Just get your plate and drive the car. Be glad to drive a car that is old enough that they don't care about enough to tax it anymore.
Damn you got a legal title, enjoy it before they make these old cars illegal.
Or not?
