I dont have any real complaints except that the 3.5 liter HO V-6 loses power when the automatic 4 speed transmission shifts from 1st into second when the gear selector is in drive, accelerating from a stopped position. However you have to place the gear selector into 3rd to achieve the second gear power boost from a dead stop. The car is well designed and fun to drive. The 3.5 liter HO SOHC V-6 is plenty peppy and the chassis is very agile. My particular car is the 2009 SXT RWD 4SPD Auto. The fuel mileage is phenomenal when the gear selector is left in drive and you keep your foot out of the fuel injectors. The car is a joy to drive.
The interior is well thought out and executed. The ergonomics and comfort factors were thoroughly designed with the taller of the human's considered. I am six foot tall and dont fit in most cars. The leather interior coupled with the power bucket seats make for a very comfortable cabin.
I know that the second gear shift points are computer controlled for fule economy, but the shift points for second need to be tweaked a little for the acceleration enthusiast.
