The current breakdown is:

2003-2007 G35 Coupe
2008+ G37 Coupe
2003-2006 G35 Sedan
2007-2008 G35 Sedan
2009+ G37 Sedan
Other Infiniti

Interior and some exterior parts do not interchange between 03-04 and 05-07 coupes or between 03-04 and 05-06 sedans. This is a particular problem when listing trim kits for aftermarket radios, as one for an 03 will not work in an 05, 06, or 07.

The breakdown should be:

2003-2004 G35 Coupe
2005-2007 G35 Coupe
2008+ G37 Coupe
2003-2004 G35 Sedan
2005-2006 G35 Sedan
2007-2008 G35 Sedan
2009+ G37 Sedan
Other Infiniti

 

I concur. The 03/04 sedan vs 05/06 sedan stuff gets annoying sometimes.

The only problem I could foresee with this is, a lot of the parts are interchangeable, so they'd have to be posted in multiple places.
