I have a chance to buy a numbers matching 1968 RS Z-28 and am curious about what they are really worth right now. I have known the owner through our local Camaro club for about 15 years, so I'm comfortable about not getting ripped off. It's a numbers matching drive train, but what bothers me is A. no documentation etc. and B. it was repainted red with white stripes. It's coded to be Sequoia Green. I'd really be more interested if it was the original color.
I've looked around online and find prices from the mid-forties all the way up into the 70K range.

If you have a Sequia Green '68, please post them. I've seen a few pictures online, but none of any quality.

I just sold mine for $42,500. It was correct color, but that's really not a big deal. Cars can always be repainted. Unless you have the docs on the 68Z, the drivetrain is the only way to verify it. I'd suggest posting pics of the trim plate and VIN#, along with pics of the motor & transmission partial VIN's...
