Roadrunner or Not

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!

Thanks. No insult taken.

I did mention that point to the man at mmcdetroit but he said that is incorrect - there were Satellites and RRs built at the Ontario plant in 1968.

So, it appears that the M (if indeed car is a Satellite) is incorrect or the F (if indeed car is a RR) is incorrect.

This may always remain a mystery.
