I have two kids and I'm able to squeeze in a double stroller with the infant and the 2 year old. Most days I drive with the 2 year old in his forward facing car seat. He sits directly behind me, I do need to make ample room when driving (I'm about 5"10 1/2") for his feet. I can always flip down the other seats with him still sitting in the back. We are moving to a new house so the room has been plenty for me, lots of room for long items and large boxes fit (even the large moving boxes from lowes fits). I came from a larger sedan (Acura TL Type-S), and the CT's room is holding up fine for me now because of the long commutes. The ES series is tempting, but I do not like the design as much as the CT. I keep getting compliments from random strangers about the CT everywhere I go.
BUT, it is 10K more than a CT and does not look as good as the CT.
