By 1994, the Testarossa was 11 years old — making it ancient in supercar years. Ferrari sent the '80s legend off into the sunset with the F512 M, the highest-performance model in the car's history, and the swan song for the long-lived flat-12 engine. The F512 M made 440 horsepower thanks to improvements like titanium con rods and a new stainless exhaust; the chassis featured suspension improvements and a new antilock braking system. Exterior styling was updated with a new taillight treatment, three-piece wheels, and a new front end. Only 501 F512 Ms were made. This 1995 model is just one of two known to have come in Canna di Fucile Metallizzato over a Beige leather interior. Passing through several owners over the years, the car has had a recent engine-out service and shows just over 14,000 miles. The car goes to auction in late January at RM Sotheby's Arizona event.
