the 3.5 has a 3.29 gear ratio and my car weighs in at 3,680 pounds. The GXP has a gear ratio of 3.71 and weighs 3,790.. So basically it is 100-130 pounds heavier, has a much higher gear ratio, and 55 more horsepower and 60 ft-lbs of more torque than my car has.

Has anyone driven a GXP with over 30,000 miles yet (and compared it to the L67 Bonnevilles.)

Drove one with 30 miles on it. Returned it with 70-something on it. That'* what I based my comment on. We'll compromise. Even up to 70mph, then the GXP will have the advantage. SSEi owns up until 70. Fair?

Since I was buying the car, I asked the dealer how much for a CD changer and he quoted over $500.

My Camaro had the wiring already in the trunk, so adding a CD changer to it was simple plug-and-play.

I too wonder if the Bonneville is pre-wired for a changer.

Since most people on this board have 3.8 engines in thier cars we will always get bias answers from them. In a few years when the GXP is more affordable for them I bet all we will hear is praise for the northstar.

I owned a 2002 SSEi before buying my 2004 GXP. The GXP has 29K on it now. I can say with absolute certainty that the GXP will beat the SSEi from 20-70 (and higher). The GXP doesn't have quite the same initial kick when you floor it that the SSEi had, but it pulls so much harder after it goes past 3000 RPMs and it keeps going to 6500, where the SSEi had to shift at 5500 and was running out of steam by then. Also, the shift points and shift feel are much better tuned on the GXP.

I loved the supercharged 3800, but the Northstar-powered GXP is clearly superior. But, as others have mentioned, the Northstar is difficult and expensive to modify, while with under $500 in modifications, you can turn the 3800 SC into a screamer that will bury the Northstar every time.

Well, I'll have to differ from experience. Having driven dozens of Bonnevilles, and owning two myself, also having driven an 04 and an 05 GXP (more than once):

There is no way a GXP will take a mildly modified S2 SSEi to the 1/4. All it takes is probably a pulley on an SSEi to beat the GXP in that regard, but considering the few GXP'* that have run at the track, it may not even take that.

Dyno numbers from INTENSE and the limited dragstrip listings so far on the GXP are dismal. To make matters worse, there is no performance aftermarket for the GXP.

Both of my Series 1 cars are quicker on the 1/4 than a GXP, and one of them is bone stock.

The long and short of it is this:

If you want a classy-looking freeway cruiser/passer, look into it. It'* a nice car, and you can get them for $26k new now.

If you want something with a little more kick around town, get an SSEi.

If you want something with a performance aftermarket, get an SSEi.

Someone said you can get them for $26... well, I paid $27,100 plus tax & plates. But that also included $2000 in GM Ccard allowance. As far as I'm concerned I got it for 30% off MSRP. I'm happy. Picked it up today. That thing can really honk. It'll be my daily driver. I don't care who'* faster, quicker, or slicker... I'm just going from here to there

I've had the vert for a couple years. Now, that'* fun! Can't wait for things to warm up so I can drive it again.

Local '05 GXP was offered to me for $26k 2 weeks ago. They hinted at a better deal for me yesterday.
