How easy is a pontiac fiero to work on-?

I think they are a little tough because rear end is compact by design and unusual engine arrangement. the common complaint this car is ultra low oil capacity, Many lost some oil and caught fire, 3 quarts when full dosn't seem like enough to me but I'm not an engineer-seems like it would be stretched thin at all times. not sure when (or if) Pontiac ever corrected that on this engine. That may be the reason they dropped the Fiero altogether but I think it was a mistake, just like Chevy giving up too easily on the Corvair. I'm not sure if you will have trouble getting parts. Hopefully another engine or updated one has readily available interchange items since the Fiero didn't last long, but perhaps others can add.
