Everything
Well laid out. Everything easy to reach. Instrument panel is interesting and informative.
For the average driver it is nimble, corners very well, "feels" like a sports car. Fun to drive.
Only Hybrid manual transmission available starting under 20,000. The base model has many "non-base" features - decent sound system, USB link, power windows, power locks, cruse, nice wheels...
In real life, potential to be much better than official ratings. My 6 speed manual current average in all winter driving (have not driven during the summer yet) stands at 43 mpg (us).
