The SH-AWD model is not a car...it's an automobile. The seats hug your body. The steering wheel grips your hands. The sound system is an on-demand DJ. And the power is to be compared to a 200 meter sprinter...not super fast... but fast. But, the coolest thing about the car is its smarts. My wife keeps her key in her bag. She attempted to put her bag with the key in the trunk and the car beeped and popped back open the truck. Oh yes, I am most certainly enjoying my 2009 TL SH-AWD. :)
The sound system. It has so many options to play music (Hard Drive, USB for (IPOD/MP3/flash drive), XM, FM, AM). It's a personal DJ. I never have to worry on the trips when I need to hear some good music. :)
If I had to improve I would make the automatic a 6 speed.
