Story
1958 Mercury Park Lane
Mercury introduced the Park Lane as its largest and most richly equipped 1958 series. The two-door Phaeton Coupe, four-door Phaeton Sedan, and Convertible Phaeton shared a 125-inch wheelbase and an extended rear body. They remain three body choices on one model-year page, not separate car identities.
430 power and Keyboard Control
The 430-cubic-inch Marauder V8 was standard with one four-barrel carburetor, dual exhaust, and a 360-gross-horsepower rating. The optional Super Marauder package raised the rating to 400 horsepower with three two-barrel carburetors. Multi-Drive Merc-O-Matic and its instrument-panel Keyboard Control were standard.
Chassis, brakes, and ride
Independent ball-joint front suspension used coil springs and a stabilizer bar; the live rear axle used leaf springs and a 2.91 final drive. Power-assisted self-adjusting drums were standard. Optional Air Cushion Ride changed the spring system and requires its own hardware and records.
Body, cabin, and proof
Park Lane-specific body codes 57C, 63C, and 76C identify the three brochure bodies. The reproduced service catalog also contains a 75B Park Lane Turnpike Cruiser entry, but that catalog-only service application is not treated as a fourth public body without corroborating sales and production records. Start with the patent plate, title, shell, and ownership history, then reconcile the 430, Multi-Drive, axle, suspension, brakes, paint, trim, options, and component dates.
Production and price boundaries
Reviewed secondary records report 9,252 Park Lanes: 5,241 Phaeton Sedans, 3,158 Phaeton Coupes, and 853 Convertibles. Published base prices were $3,944, $3,867, and $4,118 respectively. Those model-level figures do not establish one car's delivered price, option load, or surviving configuration.
