I average between 31 and 35.4 MPG which is more than twice what my SUV gets! I have "learned" how to drive in a more fuel efficient way using the MPG gauge and the fuel economy charts built into the Nav unit.
The comfort and flow of the leather and the electronics. Everything inside feels like it was well-researched and gives a wonderful driving experience. The air conditioning vents for the passengers in the back seat and the roominess were big factors for me
The JBL factory stereo is much nicer than ANY aftermarket pioneer or alpine I have ever owned. I own a DJ business and run all BOSE equipment and I am very picky about sound - The Navigation being fully integrated with blue tooth phone is a huge plus!
I test drove many hybrids before buying the TCH and I felt the Accord had the best ride UNTIL I drove the Camry. I drove the 4 cyl., the V6, and the Hybrid Camrys, and they all felt tight to the road and well engineered.
The road noise is extremely low and does not require drowning out with the stereo.
