I had a Dodge Intrepid. Worst mistake ever! Got the Impala, and was happy from the moment I bought it. Much better quality overall. The gas mileage is very impressive for a large car. I tend to be a little heavy on the gas, and average 37 mpg on the road! Overall, I average 29 mpg. I would definitely buy another one. I hope the 3.4 is as good an engine!
