Wow, a real name and place!
Ah, the extra venty look is very much a 70's thing, groovy! No wonder I didn't know the model, Plymouths and Dytonas were pretty limited to North America I think... The only Plymouths here are prime mover trucks and even those are pretty rare.
The muscle cars from the 70's in OZ were by either Holden (GM) or Ford, hahaha. And then Datsuns and Nisans a bit later on.
Darcy is based on the '70 Plymouth Superbird and the '69 Daytona Charger, which were virtual look-alikes but for a few minor differences. I loves me my Mopar muscle cars!
What model is he/she based on? I can't quite place it... Looks a bit like a Masserati, maybe a Fiat? Could even be a Datsun, or an American make like a Corvette or a Transam... The high spoiler gives it an American feel...
