I drive 65 miles a day round trip. This is an inexpensive, very dependable, and cost efficient vehicle to own. It's no frills, and it's not "plush", but it's comfortable enough on long DC area commutes, and tolerable on very long trips for one or two people. There's a surprising amount of headroom for us taller people, and the backseat area and truck are more spacious than you'd expect for such a small car.
Fuel economy - I consistently get 33- 36 MPG, normally 34. Considering the car costs around 10K less than a Prius hybrid, that's a darn good deal!
They don't make it anymore, but if they did, I'd say make it a tiny bit wider (a lot of lateral shift on taking corners fast at all), and maybe a more comfortable armrest.
