Context paragraphs:
Ferrari 288 GTO: The Ferrari GTO (often referred to as Ferrari 288 GTO) is an exotic homologation of the Ferrari 308 GTB produced from 1984 through 1987, designated GT for Gran Turismo and O for "Omologato" (homologated in Italian).

Ferrari Mondial: The Ferrari Mondial is a mid-engined, V8-powered grand tourer which was produced by Italian manufacturer Ferrari between 1980 and 1993.  Offered with coupé and cabriolet bodystyles, it replaced the Ferrari 308/208 GT4 coupé and remained the last V8-engined 2+2 model Ferrari produced until the Ferrari California convertible and GTC4Lusso coupé were released in 2008 and 2016 respectively.

Ferrari 328: The Ferrari 328 GTB and GTS (Type F106) was the successor to the Ferrari 308 GTB and GTS.  While mechanically still based on the 308 GTB and GTS respectively, small modifications were made to the body style and engine, most notably an increase in engine displacement to 3.2 L (3185 cc) for increased power and torque output.  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 lowering the engine from the vehicle.

Ferrari 550: The Ferrari 550 Maranello (Type F133) is a front-engined V12 2-seat grand tourer built by Ferrari from 1996 to 2002.  The 550 Maranello marked Ferrari's return to a front-engine, rear-wheel drive layout for its 2-seater 12-cylinder model, 23 years after the 365 GTB/4 Daytona had been replaced by the mid-engined Berlinetta Boxer.

MG EX-E: The MG EX-E is a concept car that was produced by MG and presented at the Frankfurt Motor Show in 1985.  The EX-E was a mid-engined sportscar inspired by the Ferrari 308 and designed by Roy Axe and Gerry McGovern.  The car's drivetrain and chassis were derived from the mid-engined MG Metro 6R4 rally car.  The EX-E concept car did not lead to a production version, although Gerry McGovern did go on to style the later, smaller MG F sportscar.

Ferrari 308: The name, Ferrari 308, refers to a 3 liter 8-cylinder Ferrari sports car.  There were two different Ferrari 308 models:

MG T-type: The MG T series is a range of body-on-frame open 2-seater sports cars with very little weather protection that were produced by MG from 1936 to 1955.  The series included the MG TA, MG TB, MG TC, MG TD, and MG TF Midget models.  The last of these models, the TF, was replaced by the MGA.

Ferrari TR: The Ferrari TR, or 250 Testa Rossa, is a race car model built by Ferrari in the 1950s and 1960s.  They were introduced at the end of the 1957 season in preparation for the regulations restricting sports cars to 3 litres for Le Mans and World Sports Car Championship races from 1958.  These cars dominated their competitors, with variations winning 10 World Sports Car Championship races including the 24 Hours of Le Mans in 1958, 1960, and 1961, the Sebring 12 Hours in 1958, 1959 and 1961, the Targa Florio in 1958, the Buenos Aires 1000Km in 1958 and 1960 and the Pescara 4 Hours in 1961.  These results led to World Sports Car Championship titles in 1958, 1960 and 1961 with only the Aston Martin DBR1 defeating the Testa Rossa at the Nurburgring in 1958 and at Le Mans, the Nurburgring and Tourist Trophy and the World Championship in 1959.  They were closely related to the rest of the Ferrari 250 line, including the 250 GTO.

Ferrari 308 GTB/GTS: The Ferrari 308 GTB berlinetta and targa topped 308 GTS are V8 mid-engined, 2-seater sports cars manufactured by the Italian company Ferrari from 1975 to 1985.  The 308 replaced the Dino 246 GT and GTS in 1975 and was updated as the 328 in 1985.  The similar 208 GTB and GTS were equipped with a smaller initially naturally aspirated, later turbocharged 2-litre engine, and sold mostly in Italy.

Ferrari GT4: The Dino 308 GT4 and 208 GT4 (later Ferrari 308 GT4 and 208 GT4) were mid-engined V8 2+2 cars built by Ferrari.  The Dino 308 GT4 was introduced in 1973 and supplemented by the 208 GT4 in 1975.  The cars were sold with Dino badging (continuing the Dino brand to differentiate non-V12 Ferrari) until May 1976, when they received Ferrari badging.  The GT4 was replaced by the Mondial 8 in 1980 after a production run of 2,826 308s and 840 208s.
