SoCal Challengers car club is a non-profit organization.

The Spring Festival of Lx's has its roots in Southern California as an enthusiast gathering for the hottest car platform to hit the American car market in years. Starting in 2004 (for 2005 model years), LX first referred to the new generation vehicle platform for the Chrysler 300 and Dodge Magnum. For the 2006 model year, the Dodge Charger was added. We now use the Lx designation to generically refer to first generation LX as well as now encompassing the next generation platforms for LX (Chrysler 300), LC (Dodge Challenger) and LD (Dodge Charger).
