For the price of a base, it's a great overall value for a luxury vehicle. I purchased only the leather package with automatic. Handles well, lovely interior (doesn't feel like plastic) which is important for me. I take clients out in this vehicle with good overall feedback. Base sound system is decent, includes as base a 6CD changer. Previous car was a Acura 3.2TL with a premium package; only difference I've found is that the Lexus handles better, smaller and maneuvers like a small car.
Base model is well equiped. Smart key unlock and smart key start.
