Whats the VIN and Trim Tag data. Esp the Build date from the Trim Tag. Like MrT states, VIN is problely correct. Double check the Partial VIN looking through the Passenger side Cowl Vent. it should be something like 17Nxxxxxx or 17Lxxxxxx with the N/L being the assembly plant for your car and the x's being the last 6 of your VIN Plate on the car.

If its hard to see the Cowl Panel is not all the hard to remove and replace.
