I got my sonata about 7 months ago and have approx 12000 miles on it and not one single complaint! Car is responsive, great in the rain/snow, comfortable on long trips and all around practical everyday driver! Got it during the cash for clunkers deal, and I am fully satisfied! I am steadily getting 27 mpg city / 30+ highway (I have a very heavy foot too!)
Gauge clusters, interior/exterior design, traction control, handling is exceptional for a non-german car.
Only ONE thing I would like my sonata to have--outside temp. indicator.
