With the addition of a base XE four-cylinder model, the 2008 Saturn Aura is now an even better deal than before and offers something for all types of sedan buyers, standing out as an especially sophisticated and sporty--yet frugal--sedan. At the other end of the line, the XR model, with its more powerful V6 and six-speed automatic, offers a driving experience that rivals that of luxury-brand sedans costing much more. The Green Line, as well, is attractive--and attractively priced--for those who want to minimize their fuel bills and energy use yet need a roomy sedan.
