: Looking to buy an STS, asking for some guidance

Hello everyone,

I'm in the market for an 05-06 STS. After reading a bit here and there, I learned about the options packages. I love the N*, so that is a must for me. Navi, XM, and moon roof also. SO, I understand 1SF meets those requirements. But, what is 1SG? I know it's like "The works", but what makes it so different? I pulled RPO codes for a few VINs I was looking at, and the 1SG is hard to find it seems. But the power assist steering seems interesting, so I've accumulated a few questions for you guys, I hope I'm not imposing too much....

What are the differences between 1SF and 1SG?

Are there any known issues that would be considered serious on the RWD N* platform?

What is the difference between 3.23 and 3.42 ratios? Which would be best?

It seems impossible to find ACC and HUD... Is this a 1SG exclusive?

Can I visually tell the difference between a 1SF and a 1SG by the pictures?

The power assist steering, is it more trouble than it's worth? BMWs is obnoxious, how about this?


From what I have been able to assemble, I really want a 05 or 06 1SG, red on black or black on black. Apparently, this combo is hard to find with 1SG. Also, trying to get it for under 15k, but that seems to be the easy part.

I found ONE car in California that meets this stuff. Looks clean, but it has the factory chrome 18's on it, and apparently a 3.42:1 final drive? Should I care?

1SG seems to have the adaptive steering, but I can't see any other difference other than "cooling upgrade"? What is that?

Should I give a damn about a 1SG versus a 1SF?


Thanks in advance guys, I appreciate any time you take to help me out.

May advice is that you buy an AWD (All Wheel Drive) STS. The RWD is not good in rain or snow. My next STS will definitely be AWD. I hope a few with AWD will chime in and confirm this.

I wouldn't mind the AWD version, I would love it in fact. But I live in FL so I'm not worried about the snow, and hopefully traction control would take care of most of my rain problems....but most of all, I can't even imagine how hard it would be to find an AWD 1SG black or red on black.....

Nice car, but it's about ten grand more than I'm looking to burn.

Where are you located? I am on the east coast and plan on putting my 2005 up for sale soon to get an Escalade since my family is outgrowing the STS? Your wish list sounded like my wish list when I was shopping for one and it took me a few months to find exactly what I wanted. Mine has everything and still less than 50K miles original sticker was $68k but I will want more than $15k for it. At my last oil change the dealer offered me $17k

My suggestion to you is if you want HUD & ACC you can find them but you will have to be patient and you might have to shop around for a while but its worth it. They are my favorite features on my STS. There is nothing like ACC on the highway. You set the speed and it takes care of everything for you. If someone cuts in front of you it will automatically apply the brakes and keep you at your set distance from the car in front of you. If the car in front speeds up or moves out of the lane it will accelerate for you to bring you back up to speed.

I am not certain ACC can be had on less than a 1SG. I also think the 3:42 rear-end-gear is exclusive to the AWD, but I don't think you want or need that low a gear & AWD in Florida.

The 1SG has MRC, 18" wheels, upgraded brakes, steering & mechanical cooling fan, cooled seats, more leather & wood trim, HID headlights with washers & auto high-beams. Maybe that's all available on other trim levels but probably not as common.

Take your time and you will find your car. Test drive one with & without MRC before you buy.

342 is optional on 1SF & G 323 standard and ONLY 323 on AWD

in 05-06 ACC/HUD is 1SG only

My '06 AWD 1SG has the 3:42.

My mistake. Mine's got the 3:23. Wow! The 3:42 must turn high RPM's at speed.

NP if I was wrong I wanted to know, the 342s wouldnt launch as hard but on the highway that thing would jump when you punch it!

2400 rpm @ 70 mph with 3.42.

I would expect the 3:42 to turn more rpm @ 70. I think I turn 2,000 at 60. I'll check more closely next time I'm on the highway.

I would say 3.42 would be more responsive from launch all the way up threw all gears but would limit top end due to RPM's. When I bought my 06 I had no idea it was a 1SG I just liked the car! Mine does not have ACC/HUD. It seem like every car was optioned different depending on how the dealer ordered it or in my case mine was a presold order so how the customer ordered it. There is a 06 1SG for sale in SLC Utah for 10.5K 107K miles RWD but its silver. I guess if you look long enough you will probably find one the right colors and options.

the AWD is nice. It handles nice in the snow when necessary. I live in NW Indiana (portion of snow belt). My cad is a pleasure vehicle, so for the days the roads are unplowed with 2 foot snow, I drive the 3/4 T 4x4 suburban.

EChas3
01-25-11, 09:27 PM
I took the time to check RPM & MPH closely. 2,000 RPM = 60 MPH (HUD) ~ 61 MPH (analog gage, by Cadillac spelling). This is 3.23?


If so, a 3.42 gear yields 57 MPH ay 2,000 RPM. Not very different.

AWD isnt going to be tremendously better than RWD if your tires aren't giving you any traction.
