This is going to be an early '70s Fairlady Z with a G-nose. It will not be one of the factory colors for a true 240ZG, but rather a "wish it had been offered" dark blue. It will not be getting the bolt on flares of the ZG cars either since they make the car with stock wheels (and hub caps) look anemic. It will keep the fender mounted mirrors since they go with the right hand drive. This could be a semi-clone built back in the day, or something that was done recently.
I started with the exhaust.
