Thanks to well-documented improvements in quality and reliability, Hyundai vehicles are now a better value than they've ever been. Very quietly, the Korean manufacturer has become the fourth best-selling import brand, trailing only the Japanese Big Three—Toyota, Honda and Nissan. The all-new Sonata sedan, built at Hyundai's all-new Alabama manufacturing facility, is a fine showcase of both how far the company has come and, to a much lesser degree, how far they have to go.
