I am interested in buying a new car and have narrowed my choices down..?

I am interested in buying a new car and have narrowed my choices down to a Nissan Juke, a Kia Soul, or a Hyundai Accent Hatchback. I am looking at price, ($21,000 or less, preferably) gas mileage, performance and dependability, repair record, etc. I really like the warranty on the Kia and Hyundai products. I would like feedback from people who have owned these vehicles, pros, cons, any helpful information. Thank you
