A resto-mod is a vintage car or truck that looks on the outside as if it just left the factory, but whose stock body hides numerous mechanical upgrades.

Resto-mod owners have many reasons to explain why they would spend so much money modifying a car without actually changing its appearance. Most say they have fond memories about a car they saw as a child or during their high school years. Decades later, giving in to feelings of nostalgia, they buy a similar vehicle, but find that the ride and performance were not quite what they had imagined.

Their desire to make that beautifully styled old body go, stop, ride and corner like new gave birth to a category that remains the fastest-growing trend in the collector car world.

Perry Burchfield's story is typical of this phenomenon. Six years ago, this machinist from Walland, Tenn., purchased a 1961 Ford Galaxie Sunliner - a convertible that came off the assembly line the same year Burchfield was born.

Ford produced 44,614 Sunliners in '61, but it is difficult to find a good example for sale today. The car Burchfield purchased was not exactly a prize-winner, so he bought a second one in slightly better condition. Between the two, he had enough solid parts to build his dream ride.

Tennessee-based Monday Race Cars gave the Sunliner the full resto-mod treatment by fabricating a new frame, to which the crew attached a four-link suspension in the back and a Fatman Fabrications clip in front with power rack-and-pinion steering. Grooved and ventilated disc brake rotors went on the four corners, supplemented by a power master cylinder. American Racing rims, measuring 20 inches in diameter in the rear and 18 inches in the front, were fitted with modern high-performance radials.

To power his '61, Burchfield pulled a 429ci V-8 from a Thunderbird and added a four-barrel Holley carburetor, free-flowing air intake, and other hot rod parts before applying chrome to all of the engine's exterior surfaces. He also hired a shop to custom bend the car's dual-exhaust system.

The interior was updated as well with a tilt-steering column and a full complement of easy-to-read, black-on-white gauges. The owner added power windows, an aftermarket air-conditioning system, Sand leather upholstery and matching carpet.

Hot Tamale red paint now covers every inch of the Ford's body, and all hardware, such as door handles and accent strips, were either re-chromed or replaced with new reproductions. The project took 15 months to complete.

Burchfield's Sunliner will be displayed with several other resto-mods during the Sept. 10-13 Food Lion AutoFair. Other attractions include an autograph session with Saleen Mustang creator Steve Saleen; a display of old and new Ford Mustangs, Dodge Challengers and Chevrolet Camaros; a group of customized tailfin cars; and personal rides from NASCAR drivers.
