I'm considering a LS4 powered car to replace my 2001 GP GT, which I will probably hand down to my daughter. I test drove a used GXP about a month ago and was quite impressed for the most part. I'm not really crazy about TapShift or the staggered wheel/tire set-up, but otherwise it was a very nice car.
I've been looking online at a few Monte SS cars and I was wondering if there were any other major/minor differences besides the items stated above and the obvious lack of rear doors (I could just feel barb getting ready to fly on that one, LOL)
Any tips or pointers on what to look for on a used model would be great info.
Thanks guys

Try to get an 07, better warranty.
GXP has engineer mode, which the Imala/monte lacks.
GXP is available with a NAV unit, has the staggered wheel setup, bigger brakes, and different struts.
I'm sure I'm missing some things

GXP is only 50 lbs heavier. ![Tongue](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_tongue.gif)
Maybe he means Tap, which OP said he didn't care about, the staggered wheels either. And those two are the main differences another than a more aggressive look, the bigger brakes, the Bilsteins, HUD (best thing in the world), and a bit more.
I'm biased though, the MC would be my second choice for an LS4 car, though, but only if I couldn't find a GXP.

Would a 50 lb split REALLY make that big of a difference? I like the Montes, but having the extra doors and the option to carry around more people is nice, and having more space made moving a little quicker.
Best thing I can tell you is go drive each and see which best suits you.

Just a few personal notes on the comments above:
You can VERY cheaply add factory Nav to an Impala or MCSS.
Also, it was mentioned above that the Grand Prix has the nicer interior. I think that's subjective. Actually, I think the LaCrosse Super has the nicest interior, followed by the Impala, then the Monte, then the Grand Prix. The Pontiac (to me) is just too busy inside, and the materials (like most GM interiors up to about 2007) feel excesively cheap. My mother has a 2006 Grand Prix, and the graphics are already wearing off the buttons in the center stack. Again, it's matter of personal taste, but the Impala has a much simpler interior, and while the materials are also cheap, GM seemed to do a better job of hiding that fact, at least until you touch something!
I do think the GXP has the best looking exterior.
The GXP does have a much more informative DIC and it has TAP. But from watching this site, it seems like the GXP guys have more tranny problems, too. Of course, all LS4 cars are likely to have tranny problems, if you drive hard, but it seems like the GXPs are especially susceptible. I think someone had mentioned here that using TAP often will increase tranny temps, which in turn, reduces tranny life. If this is true, it makes sense, as it's the only material drivetrain difference between the GXP and the other LS4 cars.
You also need to ask yourself about backseat space, which was a consideration for my family. The Grand Prix's fast roofline really cuts down on rearseat headroom. If no one will ride in the back, it doesn't matter. If you will be carrying passengers, it may come into play.
All that said, if I had to buy an LS4 car again, and assuming I could get a deal similar to what I got on my 2006 Impala SS (I paid $13k last May, and the car had 30k miles), I would get a LaCrosse Super. It's rarity and relative luxury make it the more appealing car.
Sorry for the long rant, but hopefully this gives you more info to make a decision.

ill give you that it is closer to the size but im still going to be a non believer when it comes to the weight, and the g8s are nice. except for that extra set of doors.
