Hello CTS-V owners ! I currently have a 2005 GTO (400 HP LS2) and love the car...but it is too "boy-racer" for me in terms of looks. I want something more business like and sophisticated..yet still has a tremendous amount of power. I am currently in the market for a 2005 CTS-V with less than 25k miles in the price range of 28K-33K. I did some research and heard that there are some fuel starvation problems during cornering and other problems with the 2004's ? and that i should look for an '05 and stay away from the '04's. Is this true ?? Any help would be greatly appreciated.

Fuel starvation? That's a first with me, unless you're talkin' about guys tracking their car with less than an 1/8 tank of gas.

Just gassed mine up from fuel starvation. Seems I have to do that a minimum of once/week. :)

so there are no advantages in buying an '05 over an '04....barring warranty reasons ?

Personally, I like the '05's antenna much better, but beyond that ... basically, no.

I have an '04 with 26k and have had no problems whatsoever! The 04 and 05 are identical, from what I have heard, except for the small external antenna as someone already said.

IMO.... This is a 100% no brainer.... You have a LS2 GTO, stick with the LS2 and get a 2006 cts-v.. You will be glad that you did... You will still be able to enjoy the broader torque range that your use to from the LS2 engine, and you will have a better differential and larger halfshafts than the 2004-2005 models... This is definantly the route for you to go!! You will also bypass a host of other misc. 2004-2005 problems, nav traffic, radiator, oil guage cluster, etc. etc.. Trust me on this one, you'll be thanking me later!! Get a 2006 cts-v. :)

Yeah,the antenna on the04 is little overkill(what's the second flexible antenna for anyway?).
I just bought an '04 last week and I got the extended warranty up to100 k miles,so even warranty was not a concern to me...

Plus, I could not have passed a later model past my wife budgeting ability :o

ahh ok. Did not know the '06 had better drivelines. Thing is, I can only afford 28k-33k...not more. Thanks for the tip though.

I can tell you that stock for stock I drove both the GTO stock and the V stock with the ls2 along with my friends vette and the torque that they claim is absolutely not noticable! They actually felt slower and me and my friend with the GTO raced from every available speed and rpm's and I beat him everytime when we both had CAI and exhaust! I even told him where to shift so it was even more of a motor race not a drivers race.
I bought my car in early '06 (with only 4k miles and warranty till mid 09) and only wanted the LS6 just from reading about the two engines. I liked it better then and like it better now still! So, you'll hear different opinions but I believe you will hear more opinions lean toward the LS6, believe it or not! I am very interested to see the reslut in this! Good luck to you either way and you will love the car regardless!

P.S. I believe superior caddy has a redline 06 with 10k mi. for $35k if you have interest in that.
About the 'drivelines' I guess you mean the rear, most have been switched to the new rear anyway!
One more thing, if you drive hard and fast, don't be gung ho about a sunroof...you'll be sorry!

There is anctually a GM Performance site, sorry lost the link. Anyway they posted dyno numbers for LS6 and LS2. The LS2 fell off on torque and HP past 6000 RPM while the LS6 stayed steady. IMHO that simply shows the LS6 at the end of its life, very finely tweaked. The LS2 will likely overcome that and surpass the LS6 but probably not in the 06 model line.

I hear you ! While the LS2 has bigger displacement (6.0 vs. 5.7 on the LS6), it's all about the internal parts ! Yes...I have heard from others that the LS6 is just more of a responsive engine that climbs quickly and aggressively through the RPM's. They also handle much much better than a GTO. I got my GTO for 22K.....I am looking at a 2004 CTS-V with 18K miles on eBay for 29K. Hmmm. I'll let u all know.

Check this, from http://www.cadillacfaq.com/faq/index.html

2004 vs 2005:

The 2004 and the 2005 are basically the same car. The 2005 car will has a few more options. The only new options are exterior colors-redline and stealth gray. Interior colors are Light Gray. Other than this, only FACTORY options are sunroof and block heater as with the '04.

New dealer options include: Cross drilled rotors, Corsa exhaust, different wheels, carbon fiber underhood dress kit, performance shocks (did I miss anything?). These are dealer installed options and basically ship in the trunk of the car and the dealer installed them before you take delivery of the car. I would get the 2004 and buy the “options” later through GM parts.

As for the price. As far as I know, the MSRP is the same between the 2004 and 2005. No, the 2005 is not more expensive (unless you add the options).

UPDATE
You must also add the addition 1300 for the Gas Guzzler tax for the 2005 CTS-V. The 2004 was exempt because it was introduced mid model year.

A list of minor changes:
1. 05 has a combined XM/onstar antenna instead of a Xm antenna on the roof and a onstar antenna on the rear glass
2. 05 has a passenger airbag sensor (light visible in rear view mirror)
3. 05 is available is expanded colors (redline/ stealth gray)
4. Later 05 models have XM nav traffic. There is really no way to tell which car expect for later in the model year production (after Janurary).

My opinion: if you can get a deal on the 2004 then do it because there is basically no difference (unless you want a new color). No harm in getting the 2004 because it is the same car.

If you have your mind set on a 2004 due to price.... Make sure you get the GM extended warranty with 100% coverage. :)

2005 CTS V with the LS6 is the only way to go..... Untill the 09 CTS V:thumbsup:

Looking at those charts, the difference between the LS6 and LS2 is nil.

Maybe 15 horse above 6500? You'll hit the rev limiter before see it. You certinaly won't feel it.

The dyno chart really shows good stuff for the LS6 as well as LS2 but I would go out and try and drive both to see for yourself! By that chart, why do we always hear about more torque from an LS2?

I will add that the LS2 will react to mods better than the LS6 but that is when getting into cam, heads and possibly a blower etc. (I haven't heard of an LS2 blown yet) That I have read in the mags and seen it first hand with a GTO.

Keep in mind that they don't have the same camshaft.. I'm pretty sure the LS2 camshaft has less lift than the LS6 camshaft. It's not exactly what i would call a "apples to apples" test. All being equal... There is no subsitute for having more cubes!!

True, more volume = more potential.

But even there we're talking 3/10 of a liter or 5% difference. Not a whole lot.

Just about irrelevant but a little more cubes for something!
