From Ford press: The 1970 Thunderbird introduced new styling featuring a long hood treatment and a unique bumper/grille that made the bumper almost invisible.
Other exterior features included a new extruded-aluminum grille (the "poke-thru nose") flanked by dual headlights. A concealed radio antenna and hidden windshield wipers and cowl air vents provided a clean, "sweeping" line from the hood to the roof, and back-up lights were "concealed" in the center rear panel.
Ultra-luxurious appointments were on the inside. Included were a standard full-width front bench seat with individual bucket-style seat backs and a fold-down center armrest.
The powertrain for the 4,551-pound car was the 429 V-8 engine and Ford’s Select-Shift Cruise-O-Matic transmission.
By 1971, Thunderbird – the name and the car – were so popular that the famed department store Neiman Marcus offered "His and Her" Thunderbirds in its catalog, which lists "gifts for the person who has everything." The twin Thunderbirds were equipped with telephones, tape recorders and other special equipment, and carried a price tag of $25,000 for the pair.
