This car does get the advertised economy. We have averaged 46.7 MPG for 21k miles. Trips often are 50+. The car is comfortable, agile, and peppy, assuming you are in the right gear. Manual shifts well, clutch is great. Instruments are clear and the MPG bars give you something extra to watch in boring traffic. I have only two complaints. First the back seat won't fold down. Second, they should have a hatchback version for versitility plus economy. All in all, a great car.
Definitely the engine. Great clutch and transmission. I enjoy the manual transmission. Being able to select the right gear helps with the small engine.
They need a hatchback version and one in which the rear seats fold down.
