This is fantastic!! This is also my favorite car. I must have build about 10 of these kits when I was a kid always trying to get it perfect. 25 years later I am back into the hobby and am building the same kit in the same color right now. I remember it being a little difficult as a 15 year old. Now, its not too bad, goes together nicely. It surprisingly has a lot of detail. My only complaints about the kit are the headlights like you mentioned, and the wheel assembly/ lack of brake rotors. What paint did you use for the turn signals on the headlights? Your build looks great man!
A few things about the Lindberg kit( build that one as a kid too), it does have accurate headlights in a 3 piece assembly with turn signals, however the engine doesn't have any turbos! So its basically just the Stealth RT. Anyway, I have attached a few pics of my current build
