Just personal preference from what I've heard and seen first hand. I know several people that have had the misfortune of owning accents and elantras back in the 90s. Yes that's a small sample size since there were a million that were made, but every single one I saw/drove/rode in/worked on/knew of was garbage. Even when they were fairly new. Were they all that bad? I'm sure not all of them, but it was enough to turn me off of hyundai forever. They didn't have one good quality other than fuel economy. The build quality was terrible, they were ugly and uncomfortable, no features, drove like crap, and fell apart at 100k.
If you go to a junkyard sometime, you'll notice that all the hyundais are generally newer and have less mileage than any other brand of car in the yard.
