Great luxury sedan, but not a good purchase.
2 years after I purchased my Sonata, used by one couple for 7 years, the engine failed. A piston rod snapped and damaged the cylinder. The top of the engine was dry due to oil not reaching it and the repairs cost more than the car is worth. It is now undrivable and I still owe on the loan. Perhaps the newer models are much better, but I do not recommend the 2007 Sonata. Positive features I can recommend are great gas mileage for a large sedan, tons of space, latch clips for children, and it is very easy to maintain. I just wished the engine would've lasted longer, but I learned a great lesson.
