Some model names associated with the Saturn L-Series include LS, LS1, LS2, LW1, LW2, L100, L200, L300, LW200 and LW300. Why the need for all of these names? I guess GM was keeping these cars fresh by renaming them each year. Maybe they were trying to disguise a poorly-reviewed model by giving it a new name. Either way, it made it impossible to tell which car name belonged to which body style and trim.
The base engine on the L-Series was an Ecotec I4, with the L81 V6 available in some years on certain models. 5 speed manual transmission or 4 speed automatic were standard.
Some of the options on the L-Series include a power moonroof and other power options.
The models with a "W" in their name denote that the car is a station wagon. Other than that, trying to figure the naming scheme is pointless. The LS cars only lasted for a short time because both Toyota and Ford made cars that were designated the "LS Series" and that market was already confused enough without help from General Motors.
I've already seen pleny of Saturn L-Series cars on the used car market. There are some really great deals online using sites like Car Classifieds or my personal favorite: EBAY!
