Been thinking about these, and know that the 03 Grand Prix's have differences from 97-02 that are odd. And James I know you've talked about this before, but I can't remember the details of what you said.

I've been coming across a few 03's that are in for what I'm looking to buy, but if there are some changes to these that are too weird then I'll look somewhere else haha.

Anybody know what things are different on the 03's only?

trans controls are the primary difference.
the Manifold Pressure Switch logic is different, and it is equipped with an Internal Mode Switch, because of this the trans connector has a different pinout than the older one's.
otherwise it's thge tried and true older style junk everywhere else without the headaches of the 03.5-early 04 heaps

its nothing id consider a drawback...on the pos side if ya blow the trans your much more likely to find a good used low mile 03-08 trans than an 02 and older

The big problem is that THEY'RE ALL 4 DOORS!!!:picard::squint::mad::bash: And, from what I have heard, the A pillars are different because they started making frame changes for the 04+ or they had put all the 02 stuff into an 04 frame to make the 03. Something along those lines is what I've heard, but have not confirmed.
