Blaine shared this rare Brazilian-made Willys Interlagos for auction.

“This 1965 Willys Interlagos Berlinette is one of fewer than 900 Brazilian-made examples built under license from Renault between 1961 and 1966, and was imported to the US at an unknown point. A refurbishment was initiated under previous ownership but remains uncompleted, and the engine has not been started. Several items of trim are missing and the fuel, brake, and cooling systems will need to be recommissioned according to the selling dealer, who acquired the car from the estate of its previous owner in January 2020. This Willys Interlagos is offered with a new front windshield and rear window, spare parts, and a clean California title listing it as a 1962 model.”
Those bucket seats look very similar, I would venture to guess with extra padding, 1965-66 Mustang front buckets.
