Nice start. I think Fujimi used a replica GTO to do their 250GTO kit. It has some strange problems. I wish they had put the vents behind the side window since most GTO's had them. Also the rear by the tail lights seems to small. Take a look at the photos of a real GTO rear end and compare. I am sure the GTO rear window could be made with flat clear sheet cut to size. It will be much clearer that the kit window. Hobby Design has a really nice phototech sheet that has all the window frames on it. You could use clear sheet for all the windows like they do on BBR kits in 1/43rd scale. Its hard to do but the results are amazing.
By the way, that first GTO photo was taken at Sebring in 2002. They had the car on display during the whole Sebring 12 hour race. They also had a tent full of Sebring winners in 2002.
