Both cars appear to be real GTO's IMO. The wood dash on the '66 is one clue. I agree with Too Many Projects, and being in CA myself, will add this: even if you can verify the VIN numbers (they will also be on the top side of the driver's side frame rail, before the rear wheel kick-up area), the cars could likely be stolen long ago, and the VIN verification will link them to where they were originally stolen from or scrapped. Say they are clean, and not stolen, you will be issued a new VIN for each car from the DMV if everything checks out. Even then, and even when restored (at a huge cost for both vehicle, easily much more than a restored car will be worth) you will end up with 2 GTO's with non-original VIN number plates, which will de-value them significantly. IMO, both are basically parts cars, and would only be worth restoring as modified cars or drag cars, and only if you did it for the love of it, without intending to re-sell and get your money back. Both cars are guaranteed money pits, and 4k for the pair is out of the question, given the missing VIN plates. With the VIN plates, they might be worth 4k, but as they sit, nowhere close.
