The Ferrari 328 GTB and GTS was the successor to the Ferrari 308 GTB and GTS. While largely based on the 308 GTB and GTS respectively, small modifications were made to the body style and engine, including an increase in engine displacement to 3.2 L (3185 cc). 7,400 Ferrari 328s were produced by the time the model was replaced by the new 348 in 1989, bringing the total for the 308/328 generation to nearly 20,000. The 328 is considered by some Ferrari enthusiasts to be one of the most reliable Ferraris; unlike some models, most engine maintenance can be performed without lifting the engine from the vehicle.
The GTB referred to the Gran Turismo Berlinetta (coupé) body while the GTS was a Gran Turismo Spider (targa top). In 1985, the 328 retailed from $58,400-$62,500 ($115,300-$123,400 in 2008 dollars) in the United States. This price included a gas-guzzler tax.
