I have the Sonata with the 4 banger. Not the high performance model at all, just a nice family type 4 door sedan. I have seen the 400 HP at the dealership and it is a nice car. I am very impressed with the Hyundai. Fit and finish is great, runs great and is well made. Made right here in the USA too, I may add. In my opinion it is a lot of car for the money. Happy Motoring!!
