So a few days ago my tranny went in my gp gxp and im sick of having to.put money into it. so is the g8 a good car and does it have any problems like the grand prix gxps have. also is there a big difference from the g8 gt to gxp ? or should i just buy the new lexus gs 350 f ? lol and stay far away from gm and its problems

I just bought a G8 GXP a coupke of weeks ago. Awesome car is my thoughts so far.
The G8s to me is like this:
std G8 v6 = Buick Regal
G8 GT = Buick Ttype
G8 GXP = Buick Grand National

The G8 GT has a 6.0 A6 tranny
The G8 GXP has a 6.2 A6 or M6 tranny

If i were you i would Get the G8 GT. I know this because i was in your spot in 2009 and i got the G8 and i love it to death. ok here is the differance between the GT and GXP

GT 6.0L L76 with L92 heads and intake has DOD that shuts off 4 cylinders :(
GXP 6.2L LS3 with L93 heads and intake and is availible in a 6 speed manuel

The DOD is not very good. Its subject to failer. IMO the weakest link in the car. DOD delete is about $1500 do it yourself or $3000 done for you. The GXP is nice and nothing really needed to be done. So if you find a good deal on a GXP take it. If not the GT with the DOD delete is right there with it

Oh brakes the G8 has smaller brakes than the GXP not a factor unless to slam on the GT at 100 or better then you get brake fade. :( replace factory rotors with slotted and dotted from brakeperformance.com and no more fade. Also take this into thought ....

HUH thats all thats hitting me right now Both are GREAT cars and react well to mods so enjoy.

Anything esle just ask.

Not much, I usually go in the Bham direction.
Yes, the brakes are upgraded on the GXP as well as the suspension.
