Hi Steve, This is a well-known - perhaps I should say somewhat 'notorious' - car with some er, baggage... I have it down in my notes as having a "re-stamped" (re-engraved?) firewall chassis number, and there has been a fair amount of gossip about the car between interested parties over a few years. I have photos of the car from when it was for sale in 2018, so it's been knocking around ostensibly 'For Sale' for a good few years now. The website you link to is actually for a somewhat parasitic forwarding company, hoping to get in on the sale of the car and the shipping/handling thereof and taking a margin from both seller and buyer. Best to look at the car with the actual seller, well-known Japanese old car vendor 'Takeey's' based in Hamamatsu City, Shizuoka prefecture. Here's their website: http://takeeys.com/index.html ...and here's the car for sale (price = 'ASK'...) on the Takeeys official site: https://www.goo-net.com/php/search/spread.php?baitai=0600834&area_cd=15&goo_car_id=700060083430240917001&ef_flag=1 Chassis number 'PS30-00218' is a genuine chassis number, but - more specifically - it is a known and official chassis number for a PS30-SB 'Fairlady Z432-R', the very limited production super lightweight variant of the 432. Genuine 432-Rs are on another level in terms of rarity, desirability and market value in comparison with 'ordinary' 432s. However, there are question marks around this particular car. You will note that Takeey's are not claiming it in writing as being a genuine 432-R. They are selling it as a '432', which it almost certainly is. The question is whether a standard 432 has been 'sexed up' with many 432-R specific parts and details and has - nefariously - assumed the identity of 'PS30-00218' which was a genuine 432-R. We can spot many 432-R specific details and parts on the car (console delete, trans tunnel-mounted ignition switch, plain vinyl trans tunnel cover, spare wheel well delete, 100 litre tank, etc etc etc - there are too many to list) but only a genuine 432-R would have the super lightweight type bodyshell with its thinner gauge sheetmetal. Almost impossible to fake that. @kats will be able to tell you much more than me, and perhaps a little more diplomatically!
