Without a Doubt a 1969 Fiat, 850 Spider!! It would not start in Hot weather, or cold weather! windows fell down, doors fell off and I bought it brand new!!!
I was so glad when it was wrecked and took a hit by the insurance company gladly. I swore never to buy a foreign car again for years afterwards. I ended up with a 1963 Chevy II nova and drove the wheels off it for 5 years without a hitch.
