My guess is that KD's '78 Eldo convertible likely has running gear problems, not having been started for several years - lubricated parts frozen in place or below good operating condition, gas tank, brake lines, electrical motor parts, suspension bushings and the like.
Since the body, interior etc. is said to be in good shape, I'd work on the mechanicals, and like you, enjoy the classy ride.
