I'm 6'3" and have no problem fitting in the car. For me the headroom is just barely enough and pretty much no one but maybe a small child could fit behind the driver's seat when I have it all the way back and adjusted to my liking. Sure the CT is noisier than an LS460, but I don't find the car to be noisy at all. Was driving an extremely quiet S-Class Benz before and I have no problems with the interior sound level of the CT. The only noise issue I have encountered is driving through deep puddles where the water hits the thin plastic wheel well liners and makes a bit of noise. Part of the wheel well liners (at least in the back) I noticed have a sound-deadening fabric-like coating. Puddle splash noises from the front might not be as loud if all the wheel well liner surfaces had this same coating.
