There are reps, but the only GT40 made in the US is from ERA in CT. All others are made overseas and imported - RF, CAV, etc. I'm sure reps from your area will post and email you.
A company named GT Supercars is located in Columbus, Ohio. I don't know anything about them except for what is on their web site. The car looks nice, though. Anyone else know about them? Does anyone have one of their cars?
