Having grown up in a '68, this will be like walking down memory lane. My uncle had one when I was a kid. A convertible. When I was 18, he was sent to DUI detox for 6 months, and I inherited the car, atleast while he was gone. And yes, I'm well aware the Z28 was offered in 69, I'm not an idiot.
Challenge Accepted.
Oddly enough, the wheel wells are wrong on the RM. Should be squared. Could just be the angle of the photos.

The GT RM version is created by Polyphony and isn't technically real so that's why they changed the body slightly. Probably more aerodynamically superior and helps make it look different than the plain Z28.
