Welcome to the forum! First, let me say the Challenger looks great & I can't wait to see more. The only real things I could nit-pick about, besides the fitment issues, would just be some small details. It is my biggest problem with the bigger scales. Being bigger, it should be easier to add smaller details, but then it drags on too long. First I would look at detail painting on things like the hood scoop openings and the front of the radiator (and core support). Then some wiring issues, like battery cables (Good job on the spark plug lines and the brake lines by the way.). Then it is just where do you stop? Valve stems on the wheels??? I can post a link to some photos of a big scale Super Seven that looks like it could be real. Don't get me wrong, I do think it looks great and can't wait to see more of your work.
