With the forecasted numbers for the 2001 and possibility of making a 2002, the '63 would be the hands down better investment. If the '63 is 100% stock/correct then $150k to $200k would probably be a good value. I saw a '67 427 coupe, which had a reasonable size production run, get $80k this weekeend on the barrett-jackson auction. A "real" '65 427 cobra, which are only slightly rarer than a '63 Z06 got $220k.
So... I ask GM, please keep the numbers down on the 2001 Z06 and do not use the name again for another 35+ years.
