Hi there!
This is my first message. I am from Spain, and a Mopar enthusiastic!!
I need some information, I have looked a lot in the web, but it doesnt match.
I explain:
I consider buying a 1968 Plymouth Valiant Signet.
So, I want to decode the VIN.
For the car, it should be a 13 digit VIN, but mine has more digits. And no one is a letter.
VH21 21 5 23 215 005591
I can think the car was not manufactured in the US.
So, any help, please???
Thnaks a lot!!
