A 1963 Jaguar E-type lightweight competition racer will lead Bonhams' Scottsdale Auction on January 19.
The car is expected to make $7.5m-8.5m.
The E-type was originally known as the "GTO Killer", in reference to its prowess on the track against the Ferrari's much feared 250 GTO series.
This example formerly belonged to Australian racing driver Bob Jane, who drove it to victory in the 1963 Australian GT Championship.
It's one of only 12 factory lightweight E-types ever built and remains in near original condition.
Jakob Greisen, Bonhams' head of US motoring, comments: "It's an honour to represent such an original and genuine example of these epic and legendary cars.
"Not only is this an incredible car by any measure, but it's also the first time a Lightweight E-Type has been offered in the US for more than 17 years."
A 1952 Scuderia Ferrari 340 America Spider competizione is valued at $7.5m-9m.
Like the aforementioned E-type this car has a prominent racing history, having competed in the 1952 Mille Miglia and the 24 Hours of Le Mans.
It was one of five cars of its specification produced by the marque. Furthermore, it's one of three to have been upgraded to factory team specifications, giving it an extra 40 horsepower.
It was later converted into a coupe, but has since been restored to its former glory.
