We purchased this car certified pre-owned with about 2800 miles on it. Besides regular oil changes and manufacturer scheduled maintenances, we have had absolutely no mechanical problems with our Sonata. It is a smooth ride on the highly and accelerates nicely compared to what we had before. More recently, we drove our Sonata cross-country, from New York state to California, and it managed superbly. The large size of the car made it comfortable for myself and three other girls for the whole trip. I would highly recommend this car.
