Nice, great price, and probably the most desirable of this Thunderbird cycle next to the 1979 Heritage. Emberglo was the default color for the Jubilee, and Thunderbirds always looked great in it.
Gage package is not common. One of my 77s had it. That one was strange as Thunderbirds go. 400 engine, airconditioning, leather interior, gage package, power windows and Polycast wheels were it. It did however have Ford's AM-FM-Quadrasonic 8-track stereo radio. As stated, strangely optioned.
Having had two 1977s with the 400, that is the single thing this car has against it. The 400 was a miserable engine, noted for oil consumption and a tendency to detonate itself out of existence. 351 or even a 302 is a much better engine for these cars.
If someone doesn't mind dealing with the 400 engine's foibles, I think they'd have an awfully nice example of 7th-gen Thunderbird in this car.
