Question: Joji Nagashima is best known for the exterior design of a two-seat convertible and coupé model which was replaced in 2002 by what?
Context: The BMW Z3 is a range of two-seat convertible and coupé models which were produced from 1995-2002.  It is the second model in the BMW Z Series, and the first of this series to be mass produced.  Initial models used the convertible body style (model code E36/7, marketed as "roadster"), with the coupé body style (model code E36/8) being added in 1999.  In 2002, the Z3 was replaced by the Z4. The first generation of the Ford Thunderbird is a two-seat convertible produced by Ford for the 1955 to 1957 model year, the first 2-seat Ford since 1938.  It was developed in response to the 1953 Motorama display at the New York Auto Show, which showed the Chevrolet Corvette.  The Corvette in turn was developed in response to the popularity of European sports cars among Americans. The Dodge Stratus is a mid-size car that was introduced by Dodge in February 1995, and was based on the 4-door sedan Chrysler JA platform.  The Stratus, Plymouth Breeze, and Chrysler Cirrus were all on "Car and Driver" magazine's Ten Best list for 1996 and 1997.  It received critical acclaim at launch, but ratings fell over time.  An updated version of the Stratus was introduced for 2001, with the Cirrus being renamed as the Chrysler Sebring, and a coupé model was also added to the range.  However, production ended at the Sterling Heights Assembly Plant in early 2006 which had built 1,308,123 Stratus and Sebrings since 2000.  The Dodge Avenger replaced the Stratus nameplate in early 2007 for the 2008 model year. The Mercedes-Benz E-Class (C207 and A207) are the respective coupé and convertible versions of the fourth generation Mercedes-Benz E-Class automobile.  Sold from 2009 until 2017 by Mercedes-Benz, the C207 and A207 replaced the previous C209/A209 CLK-Class models.  Like the CLK-Class predecessor, the C207/A207 E-Class are derived from the C-Class.  Sedan and station wagon models of the E-Class of the same vintage are built on their own platform and are known as the W212 and S212.  The coupé and convertible share a more aggressive, swifter look than the sedan and saloon, with a more svelte front and a sleeker bonnet. The Maserati Coupé and Spyder ("Tipo M138") are grand tourers produced by Italian automaker Maserati from 2001 to 2007.  They have now been replaced by the GranTurismo.  The two nameplates refer to the four-seater coupé and two-seater roadster versions, respectively.  Both models were based on the 3200 GT, which was sold in Europe, but not in the United States.  Due to the confusing nature of the names "Maserati Coupé" and "Maserati Spyder" (which could refer to any coupé or convertible Maserati has made) the Coupé and Spyder are both commonly referred to as the 4200 GT, which is an evolution of the prior model name and a reference to the increase in engine displacement from 3.2 L (3217 cc) to 4.2 L (4244 cc). 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. The Continental Mark V is a personal luxury coupe that was marketed by the Lincoln division of Ford Motor Company from the 1977 to 1979 model years in North America.  Following the success of the Continental Mark IV, the Mark V was derived from the same chassis architecture (shared with the Ford Thunderbird) with an extensive update to the exterior and interior.  The sharply-creased body introduced an exterior design theme used on many Lincoln vehicles throughout the 1980s. Nader Faghihzadeh (Persian: نادر فقیه‌زاده‎ ‎ , born 1976 in Tehran) is an Iranian-German Automobile Designer based in Munich.  He is a Car Designer at BMW Design and was responsible for the Interior Design of the BMW 7 Series (F01/F02), the Exterior Design of the BMW 6 Series Gran Coupé, Coupé and Convertible (F06/F12/F13) and the Exterior Design of the BMW 7 series (G11/G12). Joji Nagashima (born 1955; 永島譲二) of Munich, Germany is an automobile designer for BMW.  Nagashima was born in Tokyo and educated in Japan.  He is best known for the exterior designs of the E36 and E90 versions of the BMW 3 Series, the E39 version of the BMW 5 Series, and the Z3 Roadster.  He has been granted 22 patents in car design (as of Nov. 2007). The Chevrolet Beretta is a front-wheel-drive coupé produced by Chevrolet from 1987 to 1996.  The Beretta was designed in the same design studio as the Camaro and the Corvette, Chevrolet Exterior Studio 3, and was built at the Wilmington, Delaware and Linden, New Jersey assembly plants with other GM L platform models, the Chevrolet Corsica which came shortly after the Beretta, and the Canada-only Pontiac Tempest four-door sedans.  The Beretta was produced in base, CL, GT, GTU, Indy, GTZ and Z26 models.  A convertible was the pace car for the 1990 Indianapolis 500, and GM initially announced a production convertible replica, but a coupe version was offered instead.
