The Fiat 850 Spider was designed to be a sports car on a budget.The mid-60 convertible was designed by Giorgetto Giugiaro, the one who designed some other great cars as the DeLorean DMC-12, Maserati Ghibli and other concept cars.

The car ran on a 843 cc engine which produced 49 hp and had a top speed of 145 km/h. The Spider had an all wheel independent suspension, an amazing feature for those times.For a clear difference between the Spider and the basic version, aside from the more performant engine, the interior was redesigned. The car received sport seats, a leather steering wheel and a round speedometer. The instrument panel was also completely rearranged.The basic version had drums brakes on all wheels, while the Spider replaced the front ones with disc brakes.
The Spider, along with the Coupe got a refresh in 1968 due to their success on the market. Bigger engines were added, 903 cc with 52hp, the top speed increasing to 150 km/h. The new cars were named Sport Spider and Sport Coupe.

The new versions had radial tires, improved brakes and an alternator to replace the regenerator.
Previous buyers say that the biggest problem of this car was rust. Many of them were recalled even before they were up for sale.
