Beginning search/decision on a GXP

Hi, first post.

Starting to think about a GXP purchase. I've read the appropriate "stickies", and have searched the forum, but I can't find any info on the following problem:
I went to look at a 2008 Solstice GXP. The outside temp. was 90deg.F and humid. The salesman drove the car around with the A/C on and at idle the fan/engine noise was so loud, you almost couldn't talk across the closed hood! You couldn't even hear the exhaust when you stood behind the car, because of the racket up front.

First time driving or hearing a Solstice, so I don't know if this was normal or not. It was certainly a turn-off and made me re-think my desire for a Solstice.

I didn't think to check the water temp. gauge and the test drive was 110 miles away(and they would not come down in price), so I probably won't be going back.

Is this fan/engine/compressor noise normal for this car(Solstice) or not?

Any feedback would be appreciated.

Thanks, G.W.

My 2.4 (Base -non-GXP) growls louder than any vehicle with A/C that I've ever owned. There are some causes and potential fixes for this. Use the "search" box in the upper left and you'll find a couple of threads on it.

That being said, though mine is louder than I'd like, it's not so loud you can't have a conversation near the outside of the vehicle.

As others said, there's something wrong with that car. Either the fan is cracked and grinding, or the A/C compressor (if it was running) is on it's way out.

Either walk away, or only buy if you get in writing that the issue(s) will be fixed.

my 2.4 (06) had a very noisey compressior. Witch from what Ive heard was a issue on 06.apparently mine didnt get changed.( I think it was a lease car) .I added some BG products compressor quiet oil and it's much better. the fan was making a hell of a racket, so..I ordered a new one off flebay.....the new one looks great!!! and the old one is quiet as a church mouse now.......I think I might order a compressor to stick on the shelf if this one starts getting loud again....just so I dont have to change it.

Thanks all for the input.

Yeah, the car looked good but the noisy engine bay turned me off. I didn't know if that was representative of what a GXP with A/C running should sound like.

The dealer was suspect also. They had high add-on fees and wanted a NON-refundable deposit. I said "BYE-BYE", even though I drove 110mi. to check it out.

I have a feeling that my best bet is to buy private, 'cause Carfax doesn't really tell you anything and I would like to see service records & get an idea of how a car was maintained.

If anyone has any other advice for me, I am open to hear it.

Thanks again, G.W.

if youre buying it locally, within a hundred miles; you might talk with a local gm dealership service advisor and see if he has someone or an inspection he can run it thru, for cars not local this may not work. I know they have national services that will check the car out but a 10 year old turbo ?

i'd just find a mechanic locally to have someone check it if you were worried. I would think unless you are trying to buy one with mileage over 60k, the seller would consider you a serious solstice buyer and not just someone looking for a cheap convertible.

Thats just part of buying a car. I would think getting the first one you check a lucky break. You need a few to see the differences in condition plus what your willing to pay. The more you see the more you know what to look at. Dont all have to be GXP's check them all out. Buying off a lot likely has a 2-3000$ mark up on it for what they got it for. They didnt get that car from someone wanting to sell it they had to sell it. Buying private would also be a crap shoot now. Depends on how long they have been sitting on it on how they will deal. I havnt had mine that long 2 of the ones I checked out are still for sale 2 years later.

Solstice stock exhaust cant hear them till you rev it up. All my cooling fans make noise and I know their on from Truck to ATV. IMO a 4 banger cant really sound good from the engine bay. They dont sound that good from the rear either they have their own sound.

OK, here goes with some more newbie questions.

I THOUGHT I wanted a GXP. But, I really don't need the power. I want something good looking, easy to maintain & to live with, and just to cruise in.

Maybe a NA is enough for me. I really don't know. Does the NA have any advantages over the GXP (other than price & availability)? Is it quieter at idle? Is it more reliable? Is it less costly to maintain? These are things that I just don't know for sure.

Hope someone here can help with feedback.

Thanks again, G.W.

I have both, and enjoy both. I literally drive them alternately most of the time, except that the RL is the one I take out of town, mainly because it has 20k fewer miles.

Given what you say you will likely enjoy the NA since the only thing it lacks is acceleration. For all practical street purposes the handling is the same, and everything else that matters is the same.

The NA is more reliable, simply because there are fewer bits to break, and most of the issues with the GXP are with parts that aren't even on the NA.

The GXP will be noticeably louder when it starts, until it gets a little heat in it and comes off of fast idle. It also has a ticking that the NA doesn't. Not much, but it is there.

Stock exhaust note is roughly the same for both. I have the more open exhaust from a RL on my NA so it is a bit louder.

I use synthetic oil in both of mine, so the maintenance costs are pretty much the same. Otherwise the NA would be less.

I was extremely blessed to buy a cream-puff when I bought my 06' NA (sight unseen) a year ago in a private sale. Although it had been sitting up for a while and needed some TLC, it was in perfect shape. The time cleaning it up has been a joy. After getting it cleaned up, she took 12th out of the Top 25 in a car show competing against about 75 cars from Alabama, Georgia and Florida. It has not been tuned or modified - except for the cold air intake I put on it. Being an '06, it does have the clunk and whine in the differential, and the AC is a bit loud, but not unacceptable. I accept the noise from the differential as part of driving a sports car. To me, it adds to the experience. There are times I'd like to have the extra horsepower of the GXP, but in reality, the NA will go as fast as I want to go. I have a lot more fun doing 40 on a back road with the top down than I do buttoned up at 100 on the Interstate.

I love my Solstice - and I thank God for sending her to me. It has been a blessing my entire family has had the opportunity to enjoy.

I would say thats it. You will be able to find more ultra low mileage GXP's than N/A's because they use them as a luxury. Maintain the same. The option to buy either now is in your favor. A nice car is a nice car put the top down and cruise makes it a fun car. But I wouldnt think any GXP owners would trade a car in the same condition for a N/A even though they dont use max power hardly at all. The other way around would be many
