You are in the Pontiac Bonneville
What is this discussion about?
Pontiac Bonneville, Sedan

Well, the GXP wheels (Mille Miglia Evo5) that I put on my ’03 SSEi are gone. I have replaced them with some chrome 17-inch 5-spokes from American Racing. You can see them with the rest of my SSEi photos at
http://www.imagestation.com/album/?id=4290489113&idx=10 They are at photos 9 and 10. The GXP wheels had an annoying vibration at 60-80mph that my wheel and tire shop couldn’t eliminate, and they use some pretty sophisticated balancing equipment like the Hunter ground force measurement system: http://www.hunter.com/pub/company/press/2001/pr07-02-01.htm. They got the wheels balanced on the balancing equipment just fine, but on the car they vibrated. I took the car to Goodyear so they could check to ensure that the RSA tires were all OK. I watched them do the checks, and the tires were not the problem. Everyone eventually concluded that the Mille Miglia wheels, although described to me as being hub-centric wheels manufactured to Bonneville specs, were really not hub-centric. They came with “centering rings” and some very unusual looking two-piece “centering” lug nuts that neither the wheel shop or Goodyear techs had ever seen before. The net result was that although they tried several times, the wheels could not be mounted properly to eliminate the vibration. The American Racing wheels, on the other hand, are true hub-centric wheels with the center bore matching Bonneville specs exactly and using standard lug nuts. With the Goodyear RSA’s mounted on them, they run like velvet at all speeds. I'm sure Pontiac will work out any balancing kinks with the Mille Miglia wheels before they release the Bonneville GXP with those wheels on them. In hindsight I’m just as happy we couldn’t stop the vibration because I like the looks of the chrome American Racing wheels a lot better.
#3551 of 4400 Just saying Hi

I stopped by just to say hi and let you all know how happy I am with the Envoy XL. I get many compliments and really haven't missed having a Bonneville. It certainly was time for a change. There have been a couple of occasions when a Mustang or Grand Prix have cut me off or jumped in front of me just because they could; these things never happened while in an aggressive looking Bonnie.
The Envoy has more wind noise than I would like so I'm having the door seals, etc. looked into to hopefully minimize it. I must say that the solid feel and lack of rattles (so far - 5,000 miles) is impressive.
My wish was for a Bonneville SUV and this is fitting the bill.
Good luck to all and if anyone is considering an Envoy (iceman), feel free to email me.

But those miles were on our Suburban rather than the Bonneville.
We had a great vacation in Orlando and Myrtle Beach SC and the driving was enjoyable except for a major accident in NYC on the way down and very heavy traffic on Apr 25 from Orlando to Myrtle Beach. Naturally I would have prefered to be driving the Bonneville but all in all it was a great trip. PERFECT weather and lots of R&R.
I really would like to make that trip in the Pontiac but with 3 kids and loads of stuff it just isn't practical right now. Someday......

Many thanks, Ken, for the wonderful weather we had in Maine for our short trip there. It's always nice to know that someone you know can order up nice weather for you.
Boy, do I appreciate the Bonneville even more after the last two days. I took a rental Mitsubishi Lancer(no cruise control) from Chicago to St. Louis and back and got just over 30mpg. My Bonneville would have gotten close to that under the tailwind conditions. I was shocked that the POS Lancer would only get barely above 30mpg with a tailwind.

I'm glad to hear you enjoyed your trip to Maine. I've heard from a number of people that the weather wasn't so good here last week so you must have picked the best days.
Gas mileage difference between small and large cars just doesn't seem to be dramatic anymore and would suggest that more people consider the larger and more comfortable cars that we love. It's great to be able to drive our comfortable and roomy Bonnevilles and not get fleeced at the pumps.
I even averaged around 17.5 to 18 mpg in my fully crammed 100,000 mile 1995 Suburban over a good deal of my recent trip. No complaints here.

Ken, glad to hear you had a good road trip and vacation. Sorry I didn't get in touch with you while you were in Orlando. The resort you stayed at is only about four miles from my home as the crow flies. I was out of town over Easter weekend and working crazy hours the rest of the week (and I still am).
I presume you did a lot of interstate driving. I-95 is a nice, level, straight-shot from the D.C. area all the way to Florida, but there can be heavy volume at certain times of day. I recently drove up to Myrtle Beach and back and found that U.S. 17 north of Ridgeland, S.C. was much better than I-95/U.S. 378. Time-wise they were about the same but north of Charleston U.S. 17 was wide-open (nothing out there) and four-lane median-separated most of the way. U.S. 378 is single-lane for about 60 miles and there are very few passing zones (especially if you're driving the family truckster). The Bonneville would just be frustrated in traffic on that road.
Had to order some touch-up paint as I knocked a thumbnail-sized chunk off the car just behind the right-rear wheel. It's amazing how easily the paint comes off the plastic parts; I only brushed up against a corregated cardboard box in my garage.

Michael - maybe next trip we'll get together.
The drive from Orlando to Myrtle Bch on Fri Apr 25 was tedious at best. Lots of folks leaving town after Easter week vacation and it took 5 hours to get to Jax Fla from Orlando! I looked at Rt 17 as you suggest on the map and had Rt 95 not finally opened up by the time we got to Savannah I would have taken it.
Driving the Bonne would have been as frustrating as it was in the Burb but at least up high you get a better view of the miles of stop lights ahead of you

Not the definitive indicator by any stretch of the imagination but a fair indicator of the (decent) quality that one can expect from a Bonneville.
Jives well with my experience - after 2 1/2 years and 40k miles.

I am one happy and proud BONNY owner. It
is 95 Fully Loaded 3.8 regular. I just
did a 210M trip last Sunday here in TX to
Dinasaur Valley State Park(from North Dallas),
and ended-up around 30mpg. This is very
I got ~126K on odometer, the trunk was full, the
AC was on all time, and we were four people( well
two boys). Average speed was 65 I guess.
Is there any japanese "fuel efficient" car for
the same size, that can match BONNY?
Not that I know
