As the second owner of a Z10, I rarely have anyone that wants to know about my car, know anything about Z10's. Yenko's, Z11's, COPO's get plenty of press but not Z10's. Perhaps the values would go up if others outside the CRG new anything about them. If rarity is your thing, not many other 69's can lay claim to being much rarer, more desirable absolutely. So, if anyone has a 68 Z/28 Lemans Blue, white stripe, blue interior that wants to talk swap, I might listen. lol
