Pleased at 16k
 Bought car 3/08 and now have over 16k. So far no trips back to the dealer. Getting 24mpg in suburban driving and averaging 30-31 highway at 70-75mph. Very happy with gas mileage with all this power.  Continental tires have provided smooth quiet ride to go with extremely quiet engine, which compliments a great sound system.  Have found seats very comfortable for long drives.  Gauges and buttons easy to use/follow.  Trunk plenty spacious and nice having fold down split rear seats.  Worth having the leather seats (heated - works great) and the other additional options like heated mirrors.  Worth it.  Debated between the 4 & 6.  Worth it to pay for the 6 for the quiet and powerful engine
