This is actually a pic of my car. This car was built in Canada and I spent some time at the factory with the original Oze owners. I have read some of your post about quality. You have to keep in mind the plugs for these cars were hand carved by eye for the molds. You will not find exact side to side dimensions on these cars. My car is being built for the autorama show circuit thats why I have skin coated some of the body, It must be 100%. much of the skin coating you see on the roof is for the seems. You should not just sand the seems flush and apply primer, If you do you risk impressions of the seems coming up down the road. The seems should be sanded slightly below the surface and covered with Bondo (that process should be used on any glass body). All in all these are great quality bodies but will require work to make them perfect. My grill does has a small gap at the bottom but not anything like I see in you pics, and my grill looks like jewelry.
