Just wondering if this is a VC Royal made for the royal visit back in 1981? If so, it should have a build number (similar to "ER-2145" the last three numbers should be something similar to and ranging between the numbers 1 to the number 300 on the left side of the dashboard just above the glove box and another badge on the glovebox lid saying "Royal Commodore". It should have the word "Royal" in gold lettering on the rear pillar section and incorporated into the gold pinstripe. It also should be a 4 cylinder engine!
Looking forward to your reply Adam
