While looks are always subjective, there is none better in this regard for the price. When ithe Sonata was still relatively unknown vehicle, people would think it was a Lexus or a Mercedes. Paint finish and build quality is superb. Has to have the 18" wheels to look its best though. Have had more positive comments on the looks that almost any car I've ever driven.
Average 24 mpg in town and typically get 38 mpg on trips. All in a large family sedan. Uses regular gas.
Have taken several long trips with family of five and luggage. Huge trunk without shrinking rear seat leg room. Replaced a large SUV and rarely miss it. Certainly don't miss half the MPG that got compared to the Sonata!
Huge number of features often options on other brands. Long warranty. Real world prices are best value out there.
Bluetooth, traction control, side airbags, stability control, satellite radio, all standard. Other makers gouge on a lot of these features. Like the way Hyundai makes things simple by offering just a few option pacakages. Makes finding a car to buy easy and you don't end up paying a lot of things you don't want.
