The grill is definitely not cast, so it's not a slam dunk on what it is. The engine compartment and body still look like a Fiberfab or CMC, but the interior and engine grill could be almost anything. Look closely on the engine lid hinges for a molded on "INTERMECCANICA". They did the very first cars as pan-based kits before selling the tooling to Fiberfab and taking their own product upmarket.
