Nineteen fifty-eight wasn't a particularly good year for the Big Three. New car sales were lagging due to a recession, and some would say, a large dose of ugly designed into many new models. While Ford's Mercury division followed some of the questionable styling cues of 1958, the division would be remembered most for offering perhaps the first factory performance vehicle. What? A 1958 Mercury muscle car? But more on that later.
The Mercury was moderately redesigned for 1958. The product line included three models at the start of production with a fourth, the low-price Medalist, added mid-year. The 122-inch-wheelbase Monterey and Montclair models carried over from the previous year, and in an effort to gain a foothold on the high-end luxury market, the new Parklane made its debut. Riding on a new 125-inch chassis, it was a full seven inches longer than Mercury's other models. And while the Parklane gave the appearance of increased room, interior dimensions were nearly identical to the Monterey and Montclair.
The moderately priced Monterey included front fender nameplates and simple body side moldings. Montclair models added chrome-accented headlamp doors and bright rocker moldings. A Turnpike Cruiser package was available in the Montclair model and included a power operated Breezeway rear window, illuminated side lamps on the roof sail panel, and twin antennas extending forward in a pod at the upper windshield area. Mercury's entire line redesigned the front fenders and hood that provided a more massive look to the front end. The optional bolt-on "Quadri-Beam" headlamps of 1957 were replaced with quad headlamps blended into wider front fenders. The front bumper highlighted twin grille inserts with vertical bars, and new style parking lamps. Positioned in the center of the grille was a large letter M. The highly sculptured quarter panels formed a horizontal concave insert. Taillamps with spaceship-like appendages provided a futuristic look. The license plate opening was tipped at a 45-degree angle. Exhaust tips exited out of half moon openings at each corner of the bumper.
Inside, the Mercury was considered upscale. Buyers could order pleated seat covers in cloth, vinyl, or leather, and in single color or two-tone. Gauges were easy to read, and control knobs were positioned with the driver in mind. The automatic transmission was operated via Mercury's Keyboard Control panel, located to the left of the steering column. Buyers could opt for air conditioning, power windows, and a Seat-O-Matic memory power seat.
The big news for 1958 was Mercury's engine lineup. The 312 cubic-inch "Y" block was history as was the 368, and in their place were two new powertrains displacing 383 and 430 cubic inches. Marketed as the Marauder and Super Marauder, the larger powerhouse enabled the 1958 Mercury to become the first domestic vehicle to advertise a 400-horsepower engine. Both engines shared a common bore of 4.30 inches and a compression ratio of 10.5:1, and featured wedge-shaped combustion chambers designed into the block. Heads were designed to minimize hot spots by having no two exhaust valves positioned next to one another. Three horsepower ratings were available starting with the 312-horsepower 383, standard on the Monterey. Either a 330-horse 383 cubic-inch V-8 or the 360-horse Marauder 430 cubic-inch V-8 powered Montclair and station wagon models. The Marauder 430 was standard equipment in the Parklane. Power was transmitted to the axle via a three-speed manual, three-speed manual with overdrive, or a Merc-O-Matic three-speed automatic transmission.
In March, the little-known Super Marauder engine became available. Its 400 horsepower came from three two-barrel carburetors on top of the already powerful 360-horsepower Marauder engine. The Super Marauder could be ordered in any model including the relatively lightweight Medalist two-door sedan. When equipped with a three-speed manual transmission, a Mercury Super Marauder couldn't be beat and was considered by many to be the first factory muscle car. It's unknown as to how many Super Marauder Mercurys exist today, but with an estimated number less than 10, they are certainly a rare commodity.

Not long after their first event together, Bob bought a standard road-going 1968 Alfa Romeo Giulia Super, and had it restored by Classicarco in Manchester.
