There are seven variations of the 2007 Toyota Sienna, thanks to variety of trim and drive train combinations.  All models are also available with seven or eight seats.  The Sienna can be built up significantly with luxury and convenience items, resulting in a top shelf model that is not in the same price class as the base.  The XLE Limited AWD is the most well-equipped Sienna.
Every Sienna has standard items like keyless entry, power windows, front and rear air conditioning, power mirrors and locks, and a CD changer.  The Limited upgrades to a premium JBL sound system with ten speakers and an in-dash CD changer, and also adds xenon  headlights, 17 inch wheels, a moon roof, leather seats, heated front seats, a wiper de-icer, and adaptive cruise control.  Both the XLE and XLE Limited have a power lift gate and power sliding rear doors.  The Limited includes the front and rear parking sensors as an exclusive feature.
A long list of standard safety features includes ABS with Electronic Brake-force Distribution and Brake Assist, and the Advanced Airbag System with front seat-side and side-curtain airbags.  This model offers the extra security of AWD, which also comes with run-flat tires.   The Sienna receives strong crash test ratings in all categories.
The 3.5 liter DOHC V-6 is new this year, supplying the Sienna with 266 horsepower and 245 pound-feet of torque.  All models are equipped with special towing package, which enables the pulling of 3500 pounds.  Fuel economy for the AWD models is 18/23 mpg.
