Why is that? There is like 7 or 8 in my area that's for sale. Are they not all that great or what?

Thanks

$4.09/gal for regular, and $4.29 for Premium, that's why!

Yea I guess your right. I have an 05 GTO and gas is getting crazy. Other than the fuel price is the GXP a decent car?

You answered part of your question.

I have one. It's a 2007. Gas mileage is very good for a car that does 0-60 in the six second bracket. Overall, my gas mileage is about 22.5 mpg. For highway-only driving, 24-26 mpg is what I've experienced.

This GXP replaced a 2000 Bonneville SSEi, which has the same drivetrain as the GTP Grand Prix's '97-'03. The GXP outperforms the supercharged V-6 by A LOT, and consistently gets better mileage.

The 2007 Grand Prix GXP is one of the rarest of all Pontiacs ever produced. They are very different from other Grand Prix models of the same year. The wheels, brakes, front facia and grille, are a few of the differences. The sound is similar to the GTO--and performance is not far off. I have a 2004 GTO, also.

I believe the reason you see so many for sale is related to gas prices. If people knew how good they are for fuel economy, there wouldn't be so many for sale.

Nah! :grinno: With all due respect IMO lackluster performance for the cost and not exactly award winning looks. The stock L67 GTP does a lot better in gas mileage than you claim. :grinyes: The highway figures are much better than that even cruising 70-80 miles per hour all day long on the road. Plus you are limited on mods with the GXP and what the car could be capable of doing. With a '97-'03 GTP or even the '04 and up models with the SIII 3800 supercharged engine mods are not an issue either and needless to say the performance achieved will blow your doors off.

I dont know about this one. I dont doubt that a GXP will outperform a stock GTP, but the GTP gets way better milage than 22 city and 24-26 highway. Where have you been getting your info?

Oops Sorry Bob, we were both thinking the same thing at the same time, HA HA

I had an 00 GTP and it was a very nice car. I think the GXP's look like a cool car, but its like the GTO not alot of people want it and dont think much of it

I don't see how you can compare a GTO to a GXP. No comparison. :grinno: If I was in the market for a new or used car the GTO looks much better to me. But it is nice not having any car related debt. Hard to beat the LS2 engine even though probably not too economical. If I was looking for fuel economy I'd get a Honda. :grinyes:

Also, don't be surprised to find that some of the GXP owners probably traded them in for a gas guzzling SUV.

Another issue is both the GTO and GXP are history although you could say reborn in the new G8 GT which appears to be a good car for the cost, appearance and performance. :thumbsup:

tblake,
The info on gas mileage is from personal experience on my 2000 SSEi Bonneville and my 2007 GXP Grand Prix. The BEST I ever saw on the 2000 Bonneville was 27 mpg on all highway driving--250 mile trip. The BEST I saw on my GXP was 29 mpg on all highway driving--310 mile trip.

As to the comments on performance, most of you acknowledge the V8 GXP outperforms the GTP stock. But, do any of you SERIOUSLY believe the 3800 V6 can be modified to outperform a similarly modified 5.3 V8?

Wow, thats not good at all, something had to have been wrong. I can get upwards of 38mpg highway and 26 city 27-28 combined with my GTP, and I'm not feeding you guys BS either. I just drive it nice and keep it maintained.

No, I think what Bob and the other guys are saying is that there are very few mods available for the 5.3 V8 in the GXP compaired to the 3.8 SC motor. Not to mention that the mods that are available to the 3800 are very cost effective and if done right will outperform a 5.3 V8 GXP even with mods. Have you checked out Bob (bnaylor)'s GTP's timeslip at the track? Lets see a GXP even with mods accomplish that.....

how the hell are you getting 38 mpgs on a 3.8.IT not possibly.

:rolleyes:

I don't see how you can compare a Bonneville SSEI to a GTP. IMO comparing apples to oranges. The GTP was always a faster car in 0-60 mph and 1/4 mile times and had much better fuel economy both real world and EPA. Last time I checked at least a 200 lb difference in curb weight so they are both in different classes.

EPA fuel economy:

2000 Bonneville SSEI: city/hwy 17/25

2000 Grand Prix GTP: city/hwy 18/28

When my GTP was stock I used to get at least 29 mpg highway when I used to travel leisurely between El Paso and Phoenix. Over 450 miles one way. And nothing less than 25 mpg hauling ass.

Also, take note that LS4 engine found in the GXP has the Displacement on Demand (DoD) and beginning 2006 the Active Fuel Management (AFM) systems. Without it the fuel economy would be no better than a gas guzzling SUV or pick up truck with a V8. IMO that is the major obstacle to modding a GXP. Most of the owners of GXPs get no wheres near the mileage what is claimed here if you check out the LS Tech Auto Forums. :grinno:

Thanks Tim. I could not have said it better. :wink:

As far as anecdotal info to include timeslips like at DragTimes there are no GXPs that will meet or exceed my 1/4 mile times and trap speed. Plus there are GTPs both '97-'03 and '04 and up faster than mine. :eek: Not to mention the Intense Racing and ZZP/Stattama Twin Turbo GTs which are 9 sec ET.

We had a guy can't remember his member name that used to participate here that did the 1/4 mile in the low 11s with a '04 GTP Comp G. The mods were impressive. I think he graduated up to a Z06 Corvette but still has the GTP.

I know man, Its definatly wierd. I changed my pulley from stock to 3.5", changed one range colder plugs, and a 180 stat. Have a ZZP stage 1 Throttle Body because my MAF died not too long ago.

After I put the pulley on, plugs in, stat in, I filled with 92 octane and reset my DIC. I then took it on a 10-15 mile highway trip and initially my mpg went up to closer to 40, but it leveled off to 37-38 while I was cruising at 55-60mph. I couldnt believe it myself.

Just saw a commercial on TV about a new focus that boasted 32MPG highway. Thats not good at all for a small focus. Thats what I get every day commuting with an ond GTP. Weird!
