 I have now tested the car for about 10,000 miles and I'm really happy with my sonata. The mileage is awesome: 2 adults, one kid, one trunk full of heavy stuff and I managed to get 33 mpg on highway, between Sacramento and Los Angeles. Same combination between San Diego and Phoenix with a/c on and I got 33.3 mpg. Two adults, 2 hours of stop-and-go in la traffic (rush hour) and a/c on and I got 32.8 mpg. No mechanical problems so far, between 30k-40k miles. XM satellite radio is a must on long trips. I really miss the steering wheel controls for radio/mp3/XM and electrical controls for drivers seat. Other than that plenty of room for a 6' driver and 6.2' behind the driver. No kidding, that good.
