In 1964 Mercury made major changes to their Comet. What once was the mid-size economy car image from 1960 to 1963, now restyled to change the look and feel with new V-8 engine selections, new sheet metal lines and a more complex grill to name just a few.  The comet remained a close relative to the Ford Falcon. There was more than one model to choose from. Including a hardtop coupe, four-door sedan, convertible and station wagon, all with a standard bench seat and six-cylinder power. These Comets boasted decent handling and an economical purchase price. Comets were noted to be very fun and economical.

An even sportier off shoot of Comet’s top-line was the Cyclone. A hardtop coupe with standard bucket seats, console and a 289 V-8 with a four-barrel carburetor rated at 210 hp. Engine appointments included chrome valve covers, chrome air cleaner top insert, chrome oil filler cap, chrome oil dip stick and chrome radiator cap. Distinguished by less exterior brightwork, simulated chrome-reverse wheels with exposed lug nuts, a tachometer, three-spoke woodgrain steering wheel, special interior trim and chrome engine dress-up. A special insignia with the word "Cyclone" and a checkered flag adorned the lower section of the front fenders.

The Comet got a boost in its performance image when a fleet of Comet Caliente hardtops averaged more than 105 mph for 100,000 miles in Daytona. Specially built drag racing Comet's with 427 big blocks also were making some noise on the tracks.  After results of this endurance run were publicized, sales of the new Comets began to increase dramatically.  Mercury also set out to prove great durability of the comet when they competed in the East African Safari. At that time it was known as the most demanding toughest rally with over 3188 miles of the worst roads and trails in the world. Comet did not win the rally, however they did prove to have a durable automobile that was able to absorb brutal punishment and keep on going.
