You are in the Pontiac Grand Prix
What is this discussion about?
Pontiac Grand Prix, Sedan
#682 of 4457 My guess is

That the Impala has a much better structural rigidity than the Grand Prix in despite of the fact that both models are spin offs of the W-body platform. If you have ever driven or 'touched' an Impala, the doors, hood, fenders, etc have a much heavier, beefier sheetmetal than say the GP.
The Impala already meets 2003 Government safety requirements while the GP only meets 1997 standards, hence the lower safety ratings.
Keep in mind that the Y2K Impala/Montecarlo models are the newest members of the W-body family.
The time table is as follows
Buick Regal: Introduced 1997 and redesign due 2003
Pontiac GP: Introduced 1997 and redesign 2003
Buick Century: Introduced 1997 and redesign 2003
Olds Intrigue: Introduced 1998 and currently under model phase out.
Chevrolet Impala: Introduced 2000 and redesign 2005
Chevrolet Montecarlo: Introduced 2000 and redesign 2005.
The first models that will switch from the W-body platform to the all new 'Mid-Lux' platform will be the 2003 Buick Regal and Pontiac GP.

Could somebody respond to my post#670? I would appreciate whatever comments anyone has. Thanks.

I still come around here because, even though I don't own a GTP anymore, I still miss it.
sufgt--last year, as teo pointed out, I was in an accident with my GTP. It was "t-boned" by a guy who ran a redlight. From the skid marks, the cop estimated the other guy was doing between 40MPH-50MPH upon impact. The other guy was driving a late model Acura. I was hit on the passenger side and my car looked like he caught me smack in the middle of the front passenger door (although the whole passenger side looked like it took a 20 megaton blast).
Obviously, my car was totalled. But, there was no inclusion into the passenger compartment at all. Passenger side windows were "blown out" but all the other damage was confined to the outside of the car. I actually saw the door side beams on the passenger side and they did the exact job they wee supposed to...keep the other car out.
After the shock wore off, I took off my seatbelt (no airbags went off). I opened up my drivers side door, bushed off some little "beads of glass" and walked away. The other guy was taken to the hospital via ambulance. I checked up on him a couple of weeks later and he ended up being in the hospital for over a week.
Because of this incident, I took the insurance check and bought another GTP. Great cars! Safer than anything I'd seen before.
Oh yea...did we mention it was very fast, comfortable, full of features and fun to drive?
#685 of 4457 OK So you think you have detonation
Feb 15, 2001 (5:27 pm)
By now you must have put another tank of gas in right? If it was detonation originally, then it should be gone now.
Detonation is very close to pinging. In fact it sounds the same.
Excessive detonation can damage spark plugs, valves and piston heads.
The easiest thing to check is to pull the spark plugs and exam the tips.

On my 2001 GTP I did notice a thumping noise with the gas tank. Although, I assumed it was the gas sloshing around. It really doesnt' bother me too much though. Only time a notice it is when I'm backing out of the garage. Actually, I didn't know there was a plastic liner but if there is doesn't it sound like the tank would be safer in a collision?
I've had no problems with my GTP at all. It's great fun to drive.
#689 of 4457 Thumping noise
Feb 18, 2001 (5:25 am)
I've got a 2001 GTP too and have occasionally notice a thump when backing up...usually just the first time I back up. Are you saying this is due to the gas tank? Is there a fix for it?
I really didn't even think about this (or notice it lately) until I read the recent posts. I've consider my GTP to be pretty much flawless (aside from its excessive thrist!)
#690 of 4457 Still undecided
Feb 18, 2001 (8:08 am)
In my search for the perfect car I decided to rent the GP for 2 days and spend
some time with the spouse (get the feel with both of us in the seats). This was
a great move because it gave me some confidence I can survive without my High
riding sport Ut (Explorer)and have some fun in a sedan. I'm not sure the seats in
the GP were all that- felt uncomfortable on day 1 but okay day 2 with some adjusting.
The lighted door buttons are great at nite and I think the red glow dash is fun-
odd but fun. Handling on highway and country roads was beautiful, as well as
easy enough to park and get around in town. I guess I have a hard time because there
are so many sedans out there it starts to confuse you. I suppose you just have to bite
the bullet- hope you make a good choice and if not trade it in 2 years or so. Any
opinions about trade in value on the GP versus competition? Olds has some
good deals but I'm iffy about the continued service with the future (GM will be honoring
the warranty but depending on were you go the dealers could hang you out to dry).
Well owners- give me a little input here!

Mine is just a regular GTP sedan. Interested to hear about what they say is the cause of the thumping noise, please post when you hear something.
One interesting thing I just noticed. When standing outside of the car at one of the rear doors. I looked inside the car all the way across to the opposite rear door. From that vantage point I can see some light comming through the bottom front of the door. It looks like the doors don't quite seal. From the other side of the car I noticed the same thing. Anyone else have a sedan that shows the same thing?
