Believe it or not, General Motors did listen to car guys in the 1980s. Justified to the public (or more likely, the bean counters) as a mid-engined "economy" car with added sportiness, the Fiero was meant to show that GM under Roger Smith had a soul. There's no other way to explain the stereo speakers in the headrests. The Fiero also ended up being a godsend for Ferrari replica makers of the 1990s.
Add to that the fact that finding part is never a problem because of the numerous 1980s GM vehicles in junkyards across America and you have a winner. And that Fiero forum guys (and gals) are among the most helpful people on Earth. They will talk you through the cooling system issues and how to properly maintain your mid-engined, GM parts bin MR sports car.
Honestly, the Chinese should recreate these cars.
