I have 40,000 miles on the car now and drive 2000 to 7000 miles on trips. I would like a seat that is not so uncomfortable. But the 42 lo in town and 54 (as Hi as 57 hi) on the road is better than expected. On road trips it is always over 52 mpg. So, is it worth it? YES but comfort could improve. Also, a turbo or some additional power is needed.
Seat comfort and more engine horse power along with a style that is not so, "eco" would be real nice.
