The Skyliner's retractable top operated via a complex mechanism that folded the front of the roof and retracted it under the rear decklid. Instead of the typical hydraulic mechanisms, the Skyliner top used seven reversible electric motors (six for 1959 models ), four lift jacks, a series of relays, ten limit switches, ten solenoids, four locking mechanisms for the roof and two locking mechanisms for the trunk lid, and of wiring. The top itself largely consumed available trunk space, limiting the car's sales, though the mechanism operated reliably. Production totaled 20,766 units in 1957, declining to 14,713 in 1958 and to 12,915 in 1959. An electric clock was standard. Fuel consumption was around overall. The fuel tank was placed vertically in back of the rear seat, offering increased safety in a rear collision.
