You cannot put an email on BaT I have tried. They delete it very quickly. You can contact the seller. I tend to comment heavily on BaT on all Z and roadster stuff. I am SCRAPPYDO on their. I think that Z while old and unique will only reach high dollars if you get at least two preservationists bidding on it. To almost anybody else, this is a rotted car. It can be saved, but you would have to want to spend that kind of money. I mentioned it on Bat. You are only bidding on a VIN Tag.
I think if you get the right bidders in their you can hit 30k. But if you are relying on just an average guy / gal who wants a Z car, this is not even close to the right car to buy. However news of early VIN cars get out quickly and if the right people find it... well this is certainly a very original car, albeit very rusty and very dented to hell car.
