I'd go with the lexus, I'm shopping around right now as well, and I seemed to have come to the same conclusion. It is kind of hard to go on hear say, but thats all we have. I test drove the new IS sport design, lexus just dropped, it was pretty sweet. I found an offer online that said that I could get a free subscription to a few different magazines, for test driving the IS. check out the links, you'll see the IS ad on the left.
