This car has been part of a private collection until I purchased it a few weeks ago.
This car was used in an issue of Muscle Car Classics Magazine to show how the trunk and underhood of a real Z28 should look like.  I have the magazine and it goes with the car. 

I have the  protect-o-plate and Body Broadcast Sheet.  Along with this are copies of the original MSO, original Title, Bill of Sale from  Cliff Peck Chevrolet, Warranty Transfer Sheet, Sales Contract and Owner History from 1969 to present. 

They don't come any nicer and better documented than this.  A 69 Z28 with documentation is very hard to find. 

I believe the mileage to be right.  The last time the mileage was documented was 1987 at 60k miles.  At that time it was bought as part of a collection and has been driven very little since 1987.  Everything works including the clock.  Only thing thats not back to original is exhaust manifolds and pipes.  It has Jet Hot Coated Headers.
