 V6 gets 29 mpg on hwy - fantastic!  Gets less than 20 in city traffic.  Doesn't live up to the 22 mpg city listed, and I drive like a grandma.  Nice upgraded stereo sound, but I'm on my 3rd unit - it has a known defect/short that JBL can't seem to fix.  I'm hoping 3 is a charm.  A very comfortable, powerful car.  Bluetooth option is nice for hands free cell phone use.
