I really like the Fiero. I briefly owned an '84 4 cyl/4spd. A few years ago, I shopped around for a V6 Fiero, with a focus on an '88. I could not find one '88 for sale, at any price and the older models were priced out of reach. (I ended up with a '84 Supra. )
They are great cars and quite collectable. Tech II is spot-on. These cars require somewhat more care than an ordinary car because of the age and the many unusual engineering features. But it's worth it. Good Fieros, especially the '88 v6 models are collectable and getting hard to find. Your car will only go up (slowly) in value.
The '88's were significantly better cars than the '84 through 87's mostly because of a thoroughly redesigned steering and suspension systems. You see, GM did not quite fully develop the Fiero when it first came out. They had many cool features but their performance was pretty mediocre. Improvements were gradually introduced year by year. Unfortunately, it was not improved fast enough. Competitive cars, like the Toyota MR2 thoroughly eclipsed the Fiero. By '88 it was sinking fast, simply because GM did not put their best foot forward soon enough.
So GM pulled the plug on the Fiero in mid-88, because the 60,000-unit annual sales was not enough for GM to justify an entire assembly plant and development program specifically for this car. It's a real shame - Toyota (MR2) and Mazda (Miata) proved that a lower -volume small sporty car was, and is a profitable and beneficial venture.
On top of this, the Fiero really needed a rev-happy, powerful DOHC V-6 to remain competitive. Sadly, GM actually built one shortly after the Fiero went out of production - and all GM could do is stuff it into wheezy family sedans... because they killed their best small car!
