The Mercury Park Lane was introduced for the 1958 model year as a premium model line for the division. Available in two-door and four-door hardtop and two-door convertibles, the Park Lane offered the same body styles as the Turnpike Cruiser, though its distinctive "breezeway" rear window was adopted by the Continental Mark line.Sharing its chassis with the Colony Park station wagon (and Edsel Citation/Corsair), the Park Lane had a 125-inch wheelbase (3 inches longer than the standard Mercury chassis). In 1959, the Park Lane wheelbase was stretched to 128 inches (2 inches longer than other Mercurys). For 1960, the Park Lane wheelbase was again changed, matching the 126 inches of the standard Mercury line.The Park Lane was powered by a single engine: a 430 cubic-inch Ford MELV8. Initially rated at 360 hp for 1958, the Super Marauder engine option package allowed any Mercury with the 430 to increase its output to 400 hp (the first mass-production engine in an American automobile to be rated at 400 hp). For 1959, the Super Marauder was discontinued, with the standard engine rated at 345 hp, retuned to 310 hp in 1960. All Park Lanes were equipped with a 3-speed Merc-O-Matic automatic transmission.For 1960, the Park Lane saw a minor styling update distinguished by new taillamps, rear fender skirts, 5 chrome accent bars ahead of the rear wheel openings, wide rocker panel moldings, and the addition of a padded dashboard.For the 1964 model year, the Mercury Park Lane made its return as the Mercury division expanded its model line. Above the Monterey and newly reintroduced Montclair, the Park Lane again topped the Mercury line. In contrast to the previous generation, the Park Lane used the same wheelbase as other Mercury lines, differing primarily in trim.As the highest-priced, premium trim, many Park Lanes were fitted with the option of a "breezeway" reverse-slant retractable rear window (first used on the Turnpike Cruiser and the 1958-1960 Continental). In addition, Mercury offered the Park Lane with a fastback roofline as part of Marauder option package (seen on any full-size Mercury); the fastback design proved popular on its Ford Galaxie 500 counterpart.
