The 1994 Saturn S-Series confirmed Saturn's conservative approach to updating its models.  Changes from 1993 included ozone-friendly air conditioning, improved acceleration, and reduced engine noise.  In addition, Saturn produced 3500 models of the SL2 Homecoming Sedan, a limited edition trim with a pearl finish, leather/cloth seats, and wheels taken from the SC2 coupe.  Otherwise, the signature compact in the Saturn lineup maintained the same formula that established its solid reputation.  
The 1994 S-Series sticks with its 7 trim lineup from '93: the SC1 and SC2 coupes, the SW1 and SW2 wagons, and the SL, SL1, and SL2 sedans.  The coupes seat 4 while the wagons and sedans seat 5.  The SL, SC1, and SW1 get by with a 1.9 L, 85 hp I4 engine while the SL2, SC2, and SW2 get an upgrade to 124 hp.  Wagons give you 28.8 cubic feet with the back seat up and 56 with the back seat down.  The coupes still give you 10.9 cubic feet while the sedans give you 11.9 cubic feet.  Air conditioning comes as an option in all trims.
Overall, the 1994 Saturn S-Series continued a growing tradition of value and decent performance for a domestic compact.  Owners like the cargo space and durability.  However, they also mention issues with oil consumption and low quality materials used in certain parts of the car.  If you don't get your hopes up too high, the 1994 Saturn S-Series will not let you down.
