I always enjoy it when our resident armchair expert (RAE) from across the pond makes assumptions that turn out to be wrong. To assume he knows the people I speak to for my background information is the level of arrogance, Just as he has done here: "In contrast, one of your "people involved in the program" has knocked out a couple of hardback books - to great fanfare - but which are packed with enough misconceptions, mis-captions and plain old mistakes as to make them all but worthless for entertainment let alone reference material. You'd be well advised to take care in choosing your gurus." I've never spoken to or been in contact with that person, nor do I have his books. Yet again RAE has gone far off the beaten track. Even the people I have spoken to didn't have a lot of good things to say about the program manager you refer to. It's obvious from the photos from the Japanese magazines they are early cars, the cars in the pictures are instantly identifiable from the master list of the Vintage Z build. If you watch the videos @deanhuff posted links to you can see them at Pierre's shop. It's no great mystery but documented evidence. Just as they put the engines in conventionally at the beginning of the program, they got more efficient fitting rebuilt engines supplied by AER from below by lowering the car onto the assembly. Oh I forgot, RAE worships at the house of Japanese superiority and how could they be wrong having put some photos in a Japanese magazine. The VZ program was an American program, done in the USA and sold in the USA, not sure how the Japanese had much if anything to do with it.
