In 1980, Fiat shoppers had the choice of two affordable sports cars: the 124 Sport Spider (examples of which remain quite common in wrecking yards, and the X1/9. The mid-engined X1/9 featured 128 running gear and was a lot more fun to drive than its 66-horsepower (for US-market models in 1980) engine would suggest.
The X1/9 was once reasonably plentiful on American roads, but most examples disappeared before the turn of the century. You will see the occasional X1/9 in self-service junkyards these days, but not in anywhere near the numbers of the Sport Spider.
It looks like somebody started to work on the body of this car, then gave up.
Is this an air-conditioning compressor? I’m sure the owner’s manual advised drivers to use AC only on long downhill grades.
