Chassis 15271 is a 1972 Ferrari 365 GTB/4 'Daytona' originally delivered through a Montreal dealership and finished in Rosso Chiaro over a black interior. After spending the majority of its life in California, the car underwent a professionally documented engine and transaxle rebuild by Bill Badurski, longtime technical chairman of the Ferrari Club of America, which raised output to a dynoed 409 bhp. It retains its original warranty card and has covered modest mileage in careful private ownership.
