I had a 2007 IS250 that was totaled. I test drove a IS350 and a 250. I love the IS model A LOT!! I test drove a couple of bmws, benz, and a porsche. I can only say that the porsche could be the only other I would drive other than the IS. I also had a 99 RX300 as a weekend/whenever vehicle. It was nice when I needed the extra space....like 4 people in a car. I usually never have anyone sit in the back any way. My old 07 IS250 was giving me about 28mpg mixed driving around town....so I stuck with what I knew, I have my sporty ride, yeah less power, but the gas mileage is still as good!
