Question: The BMW M Roadster was designed to be the performance version of a model produced during what yers?

Context paragraphs:
BMW Z3: 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.

BMW 340: The BMW 340, subsequently rebadged as the EMW 340, was a large six-cylinder four-door passenger saloon produced at Eisenach initially in the name of BMW.  Five-door 340 station wagons were also manufactured.  It was described in 1948 as the first new car model produced in Germany after the war: despite new body panels, under the skin it was a modified version of the BMW 326 with which it shared its engine and wheelbase, and which had originally been commercialised in 1936.  The 326 had nevertheless been an innovative and well regarded product and the 340, which incorporated several improvements, was seen as a desirable car well into the 1950s.  Early years were dogged by disputes centred on ownership of the plant where it was assembled and its manufacturers’ rights to use the BMW name.  The cars later appeared badged as EMW 340s, and it was under this name that 340s continued to be sold until at least 1953.

BMW Z8: The BMW Z8 is a roadster produced by German automaker BMW from 1999 to 2003.  It was given the E52 BMW model code.

Morgan Roadster: The Morgan Roadster is a model produced by the Morgan Motor Company.  It was introduced in 2004 replacing the Morgan Plus 8.  The car is identical to its predecessor except for new modern Ford V6 mechanicals.  The new engine develops similar power, though less torque, and is slightly lighter than the Rover V8 which results in increased performance and better fuel economy.  Air conditioning is now standard on U.S. models.  Like its predecessor, the chassis consists of a standard ladder frame design and is built from galvanised steel with five tubular or box section cross members.  The body is built of steel and aluminum around an ash frame.  Suspension is traditional Morgan slider type up-front and solid axle / leaf spring at the rear.

BMW M Roadster: The BMW M Roadster was designed to be the performance version of the BMW Z3, and there were significant differences between the two variants.  The body of the Z3 M Roadster had a few differences compared to the standard Z3 models.  These included front and rear bumpers, gills, boot and mirrors.

BMW 303: The BMW 303 was a small family saloon produced by BMW in 1933 and 1934.  It was the first BMW motor car with a six-cylinder engine and the first BMW motor car with the "kidney grille" associated with the brand.  The platform developed for the 303 was used for several other BMW cars, including the BMW 309, a four-cylinder version of the 303, the BMW 315, a 1.5-litre version of the 303 which replaced it in 1934 and was built until 1937, the BMW 319, a 1.9-litre version of the 303 produced alongside the 315 from 1935 to 1937, and the BMW 329, a development of the 319 with styling based on the newer, larger BMW 326, that briefly replaced the 319 in 1937.

Abarth 124 Spider: The Abarth 124 Spider is a performance version of the Fiat 124 Spider (2016).  It was introduced at the 2016 Geneva Motor Show along with the Abarth 124 Spider Rally racing car.  Final assembly of the car takes place in the Officine Abarth in Turin, Italy, where the model specific parts are installed on the Japanese built roadster.

Mercury Eight: The Mercury Eight is a full-size automobile that was the first model produced by Mercury and was produced from the 1939 through the 1951 model years.  It was the only model offered by Mercury until the marque started producing multiple series in the 1952 model year, at which point it was dropped as a model designation.

Swan 60: The Swan 60 was designed by German Frers and first launched in 1994.  The first one produced was a highly customised performance version called Highland Fling which had notable racing success.  The model evolved into a regatta version and the cruiser/racer (this had a transom extension and increased displacement etc.) although most boats were customised to some level.  The hull moulding was used for the Swan 62 RS a cruising model to go alongside the newly designed racer/cruiser the Swan 601 however this model (the Swan 60) was effectively relaunched under Swan 62 "FD" version banner after a couple of years.

Austin Maestro: The Austin Maestro is a five-door hatchback small family car (and two-door van derivative) that was produced from 1982 to 1987 by British Leyland, and from 1988 until 1994 by Rover Group.  The car was produced at the former Morris plant in Cowley, Oxford.  Today, the redeveloped factory produces the BMW Mini.  An MG-branded performance version was sold as the MG Maestro from 1983 until 1991.  Although later models were sometimes referred to as the Rover Maestro, the model never wore the Rover badge.  A 3-box (non-hatchback) car, the Montego, was a derivative of the Maestro.
