Nice 'Vette! What does "FRC" stand for? "Fire-engine Red Corvette"?
FRC = Fixed roof coupe. Some people call it a hardtop which is correct, but some people who have the "targa" lift off roof section call their cars hardtops with a lift off roof. It really doesn't matter except when your searching for a particular car on the internet and you use hardtop in the search you get everything except a convertible, and every once in a while a convertible will sneak in too!
