for children. Nearly 10 years before their introduction, the design of the taillamps performed as side marker lamps. Design epilogue While the Turnpike Cruiser was produced only for two years, elements of its design would be adopted across several other Lincoln-Mercury vehicles. For 1958, Lincoln introduced the Continental Mark III; to distinguish it from the standard Lincoln, the Mark III was fitted with a retractable rear window on all body styles (including convertibles) borrowed from Mercury station wagons. While using a similar roofline as the Turnpike Cruiser, Continental used a reverse-slant rear window. For 1959, following the discontinuation of the Turnpike Cruiser, Mercury designated its hardtop roofline as a Hardtop Cruiser, with all Park Lanes (except convertibles) produced as hardtops. A compound-curved rear window was introduced, creating a fastback roofline, adopted by the 1960s Mercury Marauder and Mercury S-55. Following the 1960 Continental Mark V, Lincoln discontinued the retractable rear window design feature. For 1963, the design feature was revived by Mercury, making a reverse-slant retractable rear window standard on its full-size sedans (including the Monterey, Montclair, S-55, and Park Lane). In 1965, the roofline became an option and was discontinued after 1966. For 2001, the Ford Explorer Sport Trac mid-size pickup truck adopted a retractable rear window between the cab and cargo area. While vertical in design, the Sport Trac used a retracting center portion in line with the previous Mercury and Lincoln designs. Sales References Turnpike Cruiser Cars introduced in 1957
