Aura is the base, Strata has fogs and Alloys, Luna has fogs,alloys, cruise control,met trim, different seat fabric pattern,auto lights and mirror dimmer. Luna is 1k more than Strata.
Yes.. You can also get the Avensis 'Sol' which gives you leather seats and some other extra features (check out the toyota website), I think it comes in a 2.4L. Cruise control in luna is pretty handy.
