Colonial White. The second generation Thunderbirds were built from 1958-60, nicknamed the 'Square Bird', they had a new angular profile with quad headlights, they were now bigger and heavier, two feet longer than the first generation two seat roadster. The new Thunderbird was now a four seater, it was very low and now available as a fixed-roof pillarless hardtop or a convertible. To accommodate the higher transmission tunnel that was required in such a low car, Ford used it as a styling feature, building in a full-length center console featuring ashtrays, switches etc. New FE engines were also introduced in 1958. Unique for 1959 was the chrome slatted grille, the slatted look also at the rear behind the tail lights, 1959 had chrome arrows on the doors (1958, chrome vertical hashs). New for 59 was a leather seat option and now parallel leaf springs. (1958 had coil sprung rear suspension)
