2009 Toyota Prius Touring 4dr Hatchback (1.5L 4cyl gas/electric hybrid CVT)
I have nearly 6,000 miles on my Prius so far and have not yet been able to break the 41 MPG average, despite an 80 mile per day commute - this is disappointing as the sole reason for purchasing the Prius was to gain maximum fuel efficiency. My hopes are that this will change as the weather starts to warm up, but, don't you think Toyota would have accounted for cold weather in the MPG ratings? Otherwise, I enjoy driving the Prius.
Interior (all of it!) and the exterior shape of the car.
Steering wheel - remove the cross bars toward the bottom of the steering wheel for more comfortable steering. An electric adjustable drivers seat with a heater would be really nice - especially for those of us used to this luxury element buy seeking fuel efficient vehicles.
