When I was 15, I was totally infatuated with the X1/9. One of the prettiest designs ever penned for an accessible sports car IMHO.
I remember some auto show on PBS had a Camaro vs. an X1/9. Of course you know who won on the straightaways, but when it came to the twisties, the little Fiat dusted GM. (I've tried to find the show on the web but can't so far.)
My dad wanted me to talk to a local mechanic to get his opinion on X1/9s. The mech said:
"There are basically two kinds of Fiat X1/9's: Those that have caught fire... and those that will."
:crazyeyes rotfl
His opinion had something to do with the way the fuel hoses were routed in the engine bay.
Still I was undeterred by such criticism and when I got closer to 16, begged my dad to try to find one for a test drive. Dad caved in (probably just to shut me up) and dropped me off at the local Fiat dealer. We picked a used X1/9 off the lot and went off for the test drive... of course, the salesperson has to drive it off the lot.
When it came time to switch drivers, he turned off the engine. It wouldn't start again.

Fortunately it was a dead battery and we were able to push start it back to life.
I had a checklist of items that I was to explore on the car. I only got through about 1/4 cause so many things were broken on that particular example.
I finally respected Dad's advice and drove a Datsun and VW for a couple of years before finally saving up enough coin to buy a CRX-Si as my college car. But I still have a soft spot for the old X1/9's. :bow:
Anecdote from Wikipedia.... Fiat and Lancia models of the 1970s were particularly infamous for rapidly succumbing to severe structural rust. This is commonly attributed to a well-documented deal made by FIAT with the Russian government for a supply of surplus Russian steel. The Russian government supplied FIAT with large quantities of steel in exchange for the rights and tooling necessary to manufacture a clone of the recently discontinued FIAT 124 (sold under the Lada and Zhiguli names). Though superficially a good deal for FIAT, who off-loaded their old design and tooling at a hefty profit, the steel they received was of an extremely poor quality. There is also anecdotal evidence that poor planning frequently left early X1/9 body-shells un-painted outside the Bertone factory before transportation to FIAT where the rusting body-shells were simply painted over.
