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.
Location: West End of the 49th Parallel on a US 2010-ABS-Fury
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.
