Nothing wrong with the car as of yet.
I chose the Sonata mainly because of its looks and the price. It's a very stylish aggressive car. I was looking to buy another Camry, but when I went into Hyundai to test drive it, I loved it. It has so much power, 235 HP, and a big 3.3L engine. I am 6'4 and I have no problem getting comfortable in it. Gas mileage is good, its exactly what Hyundai claims. This is the perfect car for a person who wants a sports car, but has a family. I would pick the Sonata over an Accord or Camry any day.
I agree with you, I bought a Sonata 06 used with 50,000 miles one it, but still with a 60,000 mile warranty and I love my baby. It drives so smooth and when I press the gas its excels greatly. This is coming from a person that grew up with the Toyota family. But honestly, this car gas mileage might not be as good as a Camry, but it sure is a lot smoother and quieter in the long run and very comfortable for a short person like me.
