This is a good car, although a bit underpowered compare to other competitions ( Acura TL/Infiniti G35 ) the design of the interior/exterior is high quality, handles great, very smooth and quiet. Back seat is a bit small but i have no problem fitting 2 regular adults in the back. Overall excellent car for daily commute, very comfortable and smooth ride.
