The rear seat is not designed for adults over 5 feet tall. Which means unless you have kids its just more storage space.

4dr SUV 200-horsepower 3.0L V6 4-speed automatic AWD
The seats have plush cushioning, lumbar control and position control. The seats are leather/vinyl (I think leather, but not sure) with center punched suede allowing some air circulation. All good for greater comfort on long trips
