I owned a Fiat 850 Sport, and a 124 sport back in the day. I worked on a few X-19s. (shudder!)
Brand new, they were fun to drive. It was a mid engined sportscar based on the front wheel drivetrain from an econobox. I think Pontiac used a similar design in the '80s.
As has been stated before, they were (like all Fiats) prone to rusting, because they were built light, fast, and cheap.
My Fiats didn't have electrical problems, but most X-19s did.
The engine has solid lifters, and part of a tunup is adjusting the valves. In order to do this, you measure the lash with a feeler guage. If its in spec. go buy a lottery ticket, its your lucky day.
If not, you use a special Fiat tool to depress the valve spring. Remove what appears to be a steel hockey puck. Measure it with a micrometer. Do the math. Look in your box of pucks for one that is thicker or thinner and will make things right. Be careful, do it wrong and burn a valve.
This is all done while standing on your head (like a Fiero)
And parts are hard to find in the USA.
Get the picture?
That's why you never see these cars on the road anymore.
If the one in question is ABSOLUTEY PERFECT, and inexpensive, and you want something unusual for car shows, go for it. Otherwise.......
Buy a Peugot or an Edsel or a Yugo. Or another Fiero!
