I've read what y'all have said about how to tell what model z you have but I'm still trying to figure it out. I've got an 03 350z 3.5l auto with cruise control, Bose system, power seats with heat, traction control, rear view mirror has 3 garage setting an two more buttons, an a wing on the back, no brembo brakes, so any ideas

If you have leather power seats and VDC, it's likely a Touring model. The wing is likely an aftermarket addition, as there were NO wings standard on '03 USDM Zs.
