By the way, it's registered as a 1985, and I'm pretty sure it is an '85, but I don't see anywhere on the car that indicates this for sure...since the 10th digit of the original VIN is 1, and that would be 2001 by the United States VIN system...so again, this indicates to me that it's a European VIN.

Could that be why the 10th and 11th digits were swapped?
