Roadrunner or Not

Actually the State of California issued a VIN plate for the car back in 2003. I believe that is when the error occurred. It appears they may have transposed one of the letters/numbers and that's what we're trying to figure out.

Actually there are 2 numbers on that VIN that are impossibilities as stated previously:
RM23F8R245761
F = 318
R = Windsor, Ontario plant

Highly unlikely the CA DMV made 2 errors on same VIN, again obviously a fabricated number.

Good luck with your research, no insult intended!
