Despite a reputation for unreliable vehicles -- the old joke goes, FIAT stands for Fix It Again, Tony -- this car, affectionately dubbed "Kontiki," won the grueling Alger-Le Cap rally in 1952. To survive the 10,000-mile trip from Algiers to Cape Town through deserts, savannas, and tropical forests, the car endured major modification. Welded rear doors, two supplementary fuel tanks, double shock absorbers, flood lights and Plexiglas windows are some of the hallmarks of this trophy car.
