I think this car fits what I call unique but then there is the aspect of desirable. It cant be easy to break loose with $100K on something like this when you can wonder what if something in a better color comes along, and your money is tied up in this.
I know nothing about LS6s, but to me all you are getting is apparently a real one, a repaint, one that is bored out with no more room to go. Motor is a roller motor vs solid lifter, just would not be for me for $100K ish.
All my cars, my wife thinks are cool, this one she would say what is wrong with you! The interior reminds me of a nice caprice back in 70.
bring a trailer I believe got the max price right.
(had to edit my post: my wife does not like the close to mopar factory plum crazy purple 69 eldorado project I have that has its rare few made color that GM made. says its a pimp mobile color, yet its factory GM for cadillac only. that one we will disagree on

. She is making me sell it unfortunately.....it will hurt letting that go... it would go so well with my other cars with cool paint choices.... so sad
