Well we took a family trip this weekend to the DFW area (1,000 miles +/- total). I have to say that everything worked out great with the Sonata. The car had plenty of room for 2 adults and 2 kids. Even had a 3rd adult for some time on Sunday in the car. I was very pleased to see last night on the trip back that I hit 43 mpg doing 67 mph with a fully loaded car. Once I hit the 73 mph open road the mpg went down to around 41.5 mpg. Our next big trip will be driving from Kansas to Florida next spring. This Sonata puts our Jeep to shame when you compare the two. Just a two big thumbs up for the Sonata!!!!!
