I never had good things to say about Hyundai. I used to say that they overcharge for parts but they do not, at least for my car, a 2000 Hyundai Elantra. Comparing part prices from other manufacturers Hyundai parts are cheaper at least for my older car. I'm not sure about the new Hyundais.
They also have the best support for parts that I've ever seen right through their own website. I have never seen this from other car makers. I can buy parts for my old car online and have them shipped to me. They offer every single part the car has online and is quite amazing considering that they have to stock all those parts for older cars and still make them affordable. I think that if you ordered all the parts online you could probably built a car with the parts delivered.
The best part is that they have diagrams of everything and that is what I call support which is why I decided to keep the car after it's been in an accident and fix it. Another great thing is that they do not sell parts that you don't need. You can just buy the parts you need, even the smallest thing.
Here are some screen shots of the part store.
