I've had my CT200h for 2 weeks now, and while I really liked the car when I bought it, it has turned out to be better than I expected. Let's start with gas mileage: I'm getting 50 mpg (not 42). It's way comfy and easy to get in and out of. The acceleration is just fine (and I drive a lot on the highway). It's very solid and more fun to drive than I ever expected. Overall, this was a much better choice than some of the other hybrids I considered (I only drive hybrids; this is my third). And heck, there's snob appeal to driving a Lexus, too.
