(FOX NEWS) – The only 1969 Chevrolet Corvette Stingray ZL-1 convertible ever built is set to be auctioned for the first time in
January.

The Monaco Orange car is one of just two that were ordered
with the high performance ZL-1 option that year, the other
being a coupe.

The ZL-1 package was built around a version of the legendary
L-88 427 cubic-inch V8 engine that was developed for Can-Am
racing.

The car is scheduled to cross the auction block at RM Sotheby’s
Arizona auction on Jan. 26 and has a pre-sale estimate of $2.6
million to $3 million.

The only major component that’s not from the factory is the
aluminum short block assembly, which had to be replaced
under warranty during its first year on the road after the
engine blew.

A sale at the high end would make it the third most expensive
Corvette ever sold, behind the $3.85 million and $3,424,000
paid for a 1967 L88 convertible and coupe, but it is possible
this unique car could end up blowing them both away.
