The car looks different.
It appears to be a 4 door, dark tint sedan.
The license plate seems to have been moved from the back of the trunk to below the trunk, in the bumper. I hate that! I'd rather have my license plate on the trunk so I can see it more clearly.
The gas cap is on the passenger side, but it is now self-locking!
There appears to be no visible antenna.
The engine is a 3.6 liter V6.
This vehicle compares to the Pontiac G6 in the Cadillac STS performance range.
