I don't think there is any shill bidding here. This car is valuable because of what it was and what it can be made into. Is that a 10-bolt as described, or is it a 12-bolt? It looks like a 12 to me.
The axle alone is worth $1200-$1800. There are 20 bids tonight. This rusty stuff is valuable because of what it was and what it can be restored to. Camaro's are just plain precious, even as documented Camaro rust.
Here's an example from Carlisle 2006 before prices ran away.
Asking $22,500 OBO as you see the project this far along.
Firebirds are going up too. This one is a bit further along and I think the price is reasonable for what he is selling, but my wife says absolutely not unless there's diamonds included.
