My mother used to call my father's Fiat Spider his "bastard child." I learned to drive a stick on it, but it spent more time in the repair garage than it did at home and parts had to be found in Italian junkyards. One of my sisters inherited it and promptly gave it to the garage.
I still have my 1969 Fiat Spyder, aka the 124. I paid $2950 for it new in 1970 while home on leave. Black, with a red leather interior, black canvas manual top, original Blaupunkt radio. 124k owner miles on it, mint shape. I've cannibalized a half dozen or so other 124's, both the roadster and the coupe for parts. It wasn't made by Fiat, marketed by Fiat. The car was designed and made by Pininfarina. Last time I showed it, about 4 years ago, I was offered $45k. It is a fun car to drive, it's a beautiful sports car, unreliable as were most sports cars of the day, like the MGs, Triumphs, the Jag XKEs, the Corvettes, the Volvo P1800, the Saab Sonnet and most others. Even the Austin Healy's and their replicas never finished a Road Rally. Same with the AC Cobras. These days it is driven at most 500 miles per year, and it keeps increasing in value. I recently saw one in red from 1971 sell for $85k at auction. Very good condition, 170k miles. Pininfarina is now offering newly made parts to enthusiasts who are rebuilding them. It's worm and roller steering was incredibly more precise than rack and pinion, still is, making it a fun car to drive on winding roads. You had to pray you'd reach your destination, the downside. (I used to carry an extra clutch and linkage in the trunk with tools that came with the car.) It is one of the classic sports cars of the era, just coming into its own for collectors. It was one of the first cars sold in America with Perelli tires. BTW the British Morgan of the day, an all wood car, can be had for upwards of $200k. I had one in college for a summer, bought at a junkyard for $75, until it was hit by lightening and went up in smoke. Another fun car to drive, heading down hill with a steep decline, and a good tail wind the care could hit 40 mph with its two stroke engine. Felt like you were moving at 90. Some were 3 wheelers, one wheel in the back. New Morgans today start at $250k, and they are still hand built, with a 5 year back order. They still offer a 3 wheeler. They're mostly made from aluminum these days. They can be ordered with either new Corvette engines, or a custom Rolls Royce engine for an extra $50k.
There were also the 124 sedan and station wagon. For investors, it's looking like the few sedans available are becoming collector's items, selling for as low as $5k a few years ago, they're now selling for close to $40k restored, and the very few station wagons, if they hit the market are selling upwards of $70k.
