For the same reason a undocumented body shell with a BE axle is accepted as a COPO.

For the same reason a made-over Z/28 with add-on JL8 is involved in a bidding frenzy.

For the same reason a Z/28 on ebay advertised as original with an obviously restamped engine is now over $50,000.

The people now bidding on HP 1969 Camaros are the most gullible group of people on the planet. Knowledgeable enthusiasts aren't bidding on these cars. Watch for the whining when the '69 frenzy wanes and these people learn they got screwed.
