Given the amount of standard features and option packages that are available, buying a Lexus is not too complicated, and the 2007 ES 350 is no exception. Offered in one body style with either a moonroof (standard) or an optional panoramic roof, which stretches into the back seat, there’s also just one powertrain choice: a 3.5-liter V6 engine matched to a six-speed automatic transmission. With the main ingredients simplified ES 350 shoppers can focus instead on interior amenities and safety upgrades.
