I bought my 04 Hyundai "used" as a lease vehicle previously. This is the most reliable car I have ever owned. I like all of the standard features that on other models would cost extra. I have had to replace the radiator at about 90K, replaced the back brakes and rotors at about 100K, and have needed to replace headlights about every 6 months. The biggest inconvenience has been replacing the headlights, but this pales in comparison to the overall reliability of the car. I recently totaled this car (not due to the car!) . One thing that concerns me is that the airbag did not deploy in my head on collision. But I like this car so much that I am looking for another Elantra to replace it.
Cruise Control, sunroof, sharp steering, good acceleration.
Extend the life of the headlamps. Make sure those airbags are going to deploy!
