Hi, just doing some research.....what engine should i be looking for? i hear alot of good things about the 6....also know the n* is a solid motor...but does the * still burn oil?...i have a gtp., it has 260hp and 280torque....will the six return the same performance as i have now in the gtp...or is the N* the way to go? just looking to enjoy my first caddy to the fullest...thanx in advance,,,, Jason

My 2005 V8 does not burn oil at all. Go big, get the 8 and as many options as you can . You will not be wishing you got the 6 if you get the 8, but you might be wishing you got the N* if you get the six.

LL, I think most folks on this site would tell you that they love their V8 and wouldn't have it any other way, but I've found the V6 to be more than satisfactory. 255 horses is enough for me, it burns NO oil between changes, the mileage is slightly better and is about $8 grand (I think) cheaper (although I'm sure used has a lower spread.). The V6 paired with AWD is the best for me. I think the torque will be less than you're used to though.

thanks...sounds like a good plan.....just trying to find the best one...i love all the technology.....quick question...does the 05+ sts have the same memory for the seats and stuff as the older sts's....does it remember the settings for 2 drivers ..(like temp...radio stations..seat..steering wheel.etc)....cant wait to get my sts ..:bomb:

I selected the V6 as I didn't believe the V8 was worth the BIG extra $$$. IMHO the V6 is more than adequate. Plus, when I have the need for speed I have a 400HP C6 Corvette in my garage! :bigroll:

It has so many memory funcitons, I am still working on some of them. Yes, you can have them set for 2 persons. You can also input the welcome names ( maybe just nav option ?) . Not that my wife drives it a lot, but her FOB welcomes her as Queen.

My 2001 SLS did burn oil. So far with 16K miles, the 2005 does not burn a drop.

if you're looking into buying a 2008 model, go for the D.I. v6 and you wont be disappointed!

IMO I would get the six. The new six is amazing with power and sound. Very smooth and when you hit it, it F-in moves! I have an 07 STS v6 and when I drove my father's 08 demo, you notice such a difference, especially in the first two gears. If you were to go with the N*, it's just saying you have the solid v8 and 20 extra horses. I drove the v8 as well and the six is very similar to it in terms of HP, although you can't beat the sound of a v8. I would get the six and trust me, you will be happy, you can save money and still have plenty of power under the hood!


Good Luck!

Save yourself a lot of cash and go for a low mileage used V8. these cars depreciate so much the first 1-2 yrs that you can get 50% off sticker on a used car. i paid 28k for my fully loaded v8 last year. good luck

I chose the V8 because I knew from my CTS that the V6 is harsh and raspy. I've never looked back and I'm happy with my choice. In my opinion a smaller engine working its guts out is not the choice for a luxury sedan. To achieve the same peak power a smaller engine will have to be tuned for a narrower power band with the resulting requirement for more shifting by the transmission to keep the engine "on the boil". The luxury experience calls for smooth effortless power. The V6 will get the job done but it will be calling attention to itself much more often.

Porkfarm summed it up pretty well. I am on my second NorthStar, I tested a V6 before my recent purchase of same year with V*8. No regrets....and the mileage is not even worth a mention, if so....buy a Yaris. If however, a V6 is your only option due to price or whatever, don't consider it a compromise it is still a nice powerplant.

Caddy=power=luxury=performance.

I will hopefully be able to find a n* will the options and the color i want....i know the 6 is a solid choice....any option that i should be looking for that is one not to live without? also, i was reading that the 5.1 stereo dosent push out much bass....any opinions?...when i was younger i was one of those guys with the bass that shook the houses....don't need the bass that strong anymore, but would like some solid bass....thanx again for all of this info...Lets go FLYERS....

Check out CarMax online for a nice selection. I gladly paid $249 transfer fee for my '05 with 3445 miles. Also my fifth purchase from CM and second Caddy from same. My local dealer who is my service guy, couldn't come close and agreed on the great deal.

Amen. The V8 also sounds better. If you plan on changing the exhaust in the future for an even better sound, the V8 will take you much further. My '96 STS V8 sounds really good... I drove the '06 STS V6 and it was no good IMO.

As far as eBay, etc... there's also www.AutoTrader.com. If you go with eBay, check the car in person before buying. Always. Period.

Definitely go with V8.

I bought mine from a porsche/bmw/benz dealer. it was traded in for a bmw and the owner of this carlot was going to send it to auction. he does not sell or even allow domestic cars on his lot and was just looking to get wholesale on it. i happen to contact him threw the internet and drove up to where he was and bought the car. i never thought i would ever by a car like that but i have to say it worked out great.

The concensus here is go with a V8 . i had a V8 in my 2000 sts and it was great .
i now have a 2006 awd V6 with 1sc package , This package has about everything you would ever want in a car.
The V6 is adequate , but if i found one with a V8 i would of bought it . Other than that ,the car is perfect.
I have the 5.1 audio in my car , and the bass can be adjusted to whatever dergree you want . Car has a subwoofer in the back .You can also adjust for better sound aimed at the driver position. The caddy`s
depreciate quite a bit over the first two years , so the value is outstanding for a great car at a great price .
