The 2007 Lexus ES 350 comes as one model, but the buyer can opt for a huge range of equipment by selecting Premium, Premium Plus, Ultra Luxury, Pre-Collision, and Adaptive Cruise options packages. Freestanding options include park assist, a power rear sunshade, heated and ventilated front seats, a full-size spare tire, a wood and leather trim package, and DVD navigation with backup camera.

Optional equipment includes a navigation system, satellite radio (XM or Sirius), a 14-speaker Mark Levinson stereo system, Bluetooth wireless capability for cellphones, a panoramic glass roof, and radar-adaptive cruise control.

Safety features that come standard on the ES 350 include dual front airbags, a knee airbag, side-impact airbags (for torso protection), curtain airbags (for head protection), electronic stability control, traction control, antilock brakes (ABS), electronic brake-force distribution (EBD), and a tire-pressure monitor system. A new two-chamber passenger airbag is designed to stop your passenger's upper body and torso with minimal facial contact and neck stress on deployment.

The Pre-Collision package includes a radar-based cruise control system that automatically maintains a preset distance between the ES 350 and the car ahead. If the system senses an imminent collision, it retracts all the outboard seatbelts and triggers full panic-braking power at the pedal (but it doesn't close the windows and the sunroof like the Mercedes-Benz system).
