I agree with Gunslinger, "Initial quality and performance doesn't mean much now outside of rhetorical purposes like this." After 40+ or - years it's more about how the car was maintained, cared for or restored. I have a very original 1978 Avanti II and it's as solid as a rock. The mechanics, interior and body are fully operational and beautiful. I know much of the history including having talked to the original owners (the Petru brothers) and the last owner in Phoenix, who all took extraordinary care of the car. With only 55,000 thousand miles the one thing it needed was a new paint job, which is currently in progress. Even the paint was pretty good, but I wanted to take the car to another level. I can't speak of other years, but my '78 has been a dream come true and I wouldn't trade it or sell sell it.
