      Does the G8 suffers for the " reluctant to downshift" problem that plagues our "beloved" cars?

          I guess i'm joining the wagon - Been kicking around the idea with the wife about 'upgrading' out of the G6 - she said 'I am very firm that the car has to have 4 doors not 2 - other than that, go nuts'
          woooo hooooo!!
          I've been reading up on this thread and the g8 forum, they seem pretty solid - here is my question though, is it really worth the 6-8 grand jump for the GXP? There are a few GT's in my area for 22k-28k but I saw one GXP for 32k about 200 miles away. I think a GT would be more than enough though correct?

              by the time you do about $10,000 in mods to the gt you might be at the HP of the GXP. A stock gxp at the GTO dyno day I think dynode out at close to 465 RWHP.

                    Good luck

                    I conviced the wifey in getting a G8, regardless our shitty record with the 6 and all the "pontiac exitement" crap....

                    After reading, now I am having second thoughts!
                    Reliability
                    Build quality
                    Parts availability
                    MPG

                    So now, not only I would be getting in a high risk, highly problematic car, but a more expensive to use and to insure as well.
                    Not to mention that I need to spend out of the bat for a tuned TCU just to solve a OEM flaw

                      ohhh - well now its not sounding as great. Nothing 'huge' like power steering going out at 70 mph but lots of little things and a lot of talk about the transmission being an issue and that even after tunes they are still not 'right'. . .

                      I just want to get a car, put window tint on it and drive LOL

                        Re: What to look in purchasing a used G8?

                        First things first, a stock gxp g8 will not dyno 465. that is with a cam and full bolt-ons. Gxp's make 415hp stock at the motor. its an ls3 with no afm/dod. so a cam swap is much easier to do then on a gt(dod hardware has to be removed).
                        I dyno at 363 hp with headers exhaust and a tune. a gxp stock will make that. You do get better suspension and brembos upfront. But id rather by a gt for 10,000+ cheaper and mod up from there.
                        if you go on grrrr8.net and go under the for sale section, there are some very nicely modded g8's for sale at awesome prices. Thats your best bet.

                          rarity of car=rising/maintaining initial purchase price. They are great cars and tons of people want em.

                          Me personally, id look on some G8 boards for people trying to get rid of em. lots of people just DD'd them and did like an intake and want to move on already (why i have no idea) so id shop there.

                            If you want something to mod, get a GTO or G8. You won't be stuck in a box as far as mods to do. And the trans tune isn't a must. It drives pretty nice. Although it would help and I will be getting tuned soon. I love my G8
