"I thought that this engine was new in 2005?"
 
The DoD version of the 5.3L V8 was new in 2005.
I believe that " erichthecatt" is referring to the Bonneville GXP w/North*.
- Ray
Looking forward to driving 600+ miles this coming (long) weekend.
At many (s)miles per gallon . .

Thanks Ray. I should have stated Bonneville. I was thinking of a taller tire. While i was sitting at a casino in vegas trying to win an 06 chrysler 300 for 15 cents, i noticed that the car had goodyear 225/60/18. It looked like quite a bit more rubber height. Does anyone know where i can go to compare the two tires? I dont want to mess up the speedo

I did some checking on Tire Rack's site, and found the difference. Some 225/60 x 18 are the same diameter as the stock fronts, and others are about 1.5" inches taller; it strictly depends upon brand. This would equate to about a 6% difference for a wide spread between the two. That would mean it would read 100 MPH, when it's really going 106 MPH. Not that bad at all.

If you want to soften up the ride, don't mess with the size of the tires. Pick a tire that is aimed at a quieter/softer ride instead of one that is fairly skewed towards performance. For example, for the front, Continental ContiProContact in original size are only $126 at the Tire Rack and rate very quiet, and nice riding, while not totally giving up handling. Or some Pirelli PZero Nero M&S but those are a lot more money.

I have 11,500 on my 2006. I have gotten as high as 26.5. When I first got the car, I was getting 13-14. I was really surprised at that. But, I think, as you put more mileage on your car, you'll get better mileage. I did. I'm satisfied. I knew that when I bought the car the mileage probably wouldn't be as good as my 3 GTP's but I didn't care; I wanted this 8 cylinder and I also knew the gas prices would be high, but I didn't care about that either. Except for my hissing/humming I love the car. I can't help it if I'm a fanatic about my car. I said to the dealer I think I'm paranoid. They said, "you think?" They also told me to stay off of the Edmunds website. You can't believe everything you read!! Oh, well. Good luck with your car. What color is it? I like the fact that you don't see yourself coming and going. I've only seen one in a grocery store lot so far. When I first got the car and drove it down to South Jersey, my brother surprisingly said he liked it. That was quite a compliment coming from him. He used to race hsi 65 GTO. He had to check under the hood to see how they set everything up in this 8 cylinder. He was making me nervous and then all of a sudden he pulled a rag out. When preping it, the mechanic at the dealership left a red rag on the bar in front of the fan. My brother said it's a good thing it wasn't in the fan! It was red so he could see it easily. He was disgusted with that, though. Chats1

My GXP has 11,000 miles, I just took a 1500 mile trip with it. Speed was average of 80mph, mpg varied from 20.5 - 23, depending on when I had a head wind. If you can keep it below 70mph, you might do better, but I can't do that!

Lets see, 2200 miles, so far. Mostly drive to work about 15 miles each way. About 10 freeway, 5 city and I have gotten from 20.5 to 23.7 for a high. The more I drive highway the better. Usually do cruise or I speed way too much. About 65 or so and the cruise does a better job of getting MPG and DoD shut off then my foot. Any significant increase in city driving side trips reduces the mileage to the low side 19-20. Running mid-grade gas, don't know if that makes a difference on mileage. AC always on, it is already 90-100 everyday. Plan a long trip later in the summer and will let you know. But for the simple fact I have a car with so much fun to drive the fact that I get 20s MPG is GREAT. I mean fullsize, comfortable, great handling, acceleration, all for something that gets in the 20s consistently. It is only costing me 3-4 gallons more a week (about $12) over my 03 Civic SI with significantly greater comfort, less road noise, better sounds, more power....Not too shabby.
 
PS Sorry to offend the younger drivers, this old man (39), still would like to see the total buyer age stats.
 
Cheers,
Gary

My Dark Cherry has the graphite leather interior. I wouldn't like the tan either. About the ac, I use mine all the time -- it works great, nice and cold -- no problems with it at all. That would have been my first complaint, before the hissing!!! Oh, I have everything too except for the nav. system. Chats1
