Question: Which smallest Oldsmobile product was the base package for the Oldsmobile 442?

full_context: Document 1: TVR 420 SEAC: The TVR 420 SEAC is a sports car designed and built by TVR between 1986 and 1988. It is considered as the ultimate "wedge" TVR and is the final of TVR wedge family. Unlike the other wedges the 420 SEAC was different. The acronym SEAC stands for Special Equipment Aramid Composite, that means that more than 20% of the body was kevlar unlike the others wedges full fibreglass construction. The use of kevlar made the car more than 100 kg lighter without compromising the body rigidity. That, in addition to the highly tuned Rover V8 engine made the car extremely quick but had its effect on price which was twice as much as a standard 350i. In addition the SEAC models can be distinguished by the large rear spoiler and the rounder nose. By 1988 when the 420 SEAC was replaced by the even more powerful 450 SEAC about 40 cars had been built.
Document 2: Oldsmobile Cutlass: The Oldsmobile Cutlass is a line of automobiles produced by Oldsmobile between 1961 and 1988, and again briefly in 1997-1999.

The all new Cutlass began as a unibody compact car, but saw its greatest success as a body-on-frame intermediate.

It was assembled at the Toledo North Assembly Plant in the United States, as well as in other countries including Egypt and Venezuela. The Liberty ceased production on August 16, 2012.

Introduced as an option package for US-sold F-85 and Cutlass models, it became a model in its own right from 1968 to 1971, spawned the formidable Hurst/Olds in 1968, then reverted to an option through the mid-1970s. The name was revived in the 1980s on the rear-wheel drive Cutlass Supreme and early 1990s as an option package for the new front-wheel drive Cutlass Calais.
Document 7: Trans-Am production cars: Trans-Am production cars were factory-built pony cars based on vehicles raced in the Sports Car Club of America Trans-Am Series. These cars were used largely for homologation purposes, but also as promotional tools for the series. The first Trans-Am street car was Chevrolet's Z/28 Camaro, which entered production in 1967. By 1970 six makes were producing street cars based on their racing vehicles. Due to their low production numbers and high performance, these vehicles are highly collectible today.
Document 8: Dodge Warlock: The Dodge Warlock, originally a concept vehicle and part of Dodge's late 1970s "adult toys" line, is a wheelbase truck that was produced in limited production in 1976 and regular production from 1977 to 1979. They were available in 4x2 and 4x4 models. The 4X4 models were named Power Wagons. The 1978 models were offered only in black. There were utiline trucks available in any color. The warlock only came in black. Its main draw was that it was a factory customizable truck, also known as a "trick truck", and was designed to appeal to young 4x4 buyers. The Warlock featured custom wheels, wide tires, bucket seats, a Utiline bed, and oak racks for the bed. Optional equipment included five-spoke wheels, bucket seats, tinted glass, bright rear bumper, and power steering. All had black interiors accented by gold tape on the dash and the doors, and a "tuff" steering wheel. Like the standard pickups, it had front disc brakes, and a standard slant six or a V-8. The exterior was accented by gold pinstriping around the wheel wells and the body lines. the pinstriping continued inside onto the doors, dashboard, and instrument panel. Warlock was printed in gold on the tailgate. The 1979 model however is different in that it has "Warlock II" printed on the tailgate. It appears that all normal engine options were available. It could have come with the standard Slant six, the 318 with either the 2 barrel or 4 barrel carburetor, the 360, the 400, or the 440. The 318 appears to be the most common engine selected.
Document 9: Mercury Lynx: The Mercury Lynx is a compact car that was produced by Mercury for model years 1981 to 1987. It was a rebadged version of the Ford Escort. In 1987, the Lynx was dropped after slumping sales (although at one point, it was Mercury's best-selling car). In 1988, Mercury launched the Tracer as the Lynx's replacement. The Tracer was based on the Mazda 323, was built in Mexico and Japan (depending on model), and shared nothing with the Lynx.

He was revered in the automotive industry as a visionary ahead of his time. Throughout his career, Beltz became known as much for his engineering brilliance as his charisma, his always clever sense of humor and impeccable taste in cars. According to legend, John Beltz and his staff led Oldsmobile through undoubtedly its best years and the Oldsmobiles from 1949 to 72 define Olds as the Rocket division of GM. It is said that during his time at the helm of Oldsmobile, Beltz represented Michigan and the auto industry in its purest form, when cars were king and the auto industry worker, both blue and white-collar, was the lifeblood of the state.
