The last letter designates the model year, The CXA means a CX (Fury)model from 2010, the CXAB is a CXA (ABS Fury) from 2011, a 2012 would be CXAC and the 2013 is CXAD (ABS models) and CXC and CXD for the standard model.
Thanks John. Makes sense, same as the 10th place in the VIN . Been scratching my head over that one since 2009 . Many 'for sale' ads for the 2010 non ABS Fury listed it as a VT1300CXA while others left the A off and now I know why.
