What year?

[Jeff B]

I would guess 05.

03 has different OnStar antenna than 04 to 06, this appears to be the 04-06 type
03 and 04 had rear orange turn signals, this one does not
06 has red lights in rear bumper, this one does not

2005, OR a 2003/2004 with 2005/2006 tail lights

Asking, because of the absence of yellow turn signal and seller tell it is a 2003?

Hey vador,

I have an '04 and I bought the '05 taillights on e-bay, so it's possible

Is it yours, if so then it is possibly an 05 - just going by the sig line - I hope this helps you out.
