I had a 1961 Fiat 600D. Very primitive but cheap to own and easy to work on. Got me through 2 years of college, although something of a PITA at times. I still have fond memories of it.
The interior was pimped out with upholstered panels, nice carpeting and so forth, and everybody thought the suicide doors were cool. Otherwise the car was pretty much a piece of crap and I don't remember keeping it more than a couple months. The least amount of time I kept a car was my fourth car, a '61 Fairlane that that was so bad I got rid of it the same day I bought it.
