I know, I know, these type of topics get beaten to death but I appreciate the feedback.

Looking at two cars, one 06 CTT-S that is a 1 owner car with 90k. The other is an 08 TT, 2 owner car with 64k miles.

The 08 has PDCC, lower miles and the 4.8L but not sure if that's a plus or not.

Is a 957 with PDCC worth the extra $6k or so that they are going for?

Power is about the same between these two but just wondering for reliability and PDCC advantage.

 

Pick the car that's in better condition. I've never driven a car with PDCC but have been told its magic. There is some additional maintenance involved with that system that you should be aware of.

I bought my '06 CTTS with 109k on it, has 126k now. Had to do some normal maintenance (and replace the torque convertor seal right after I bought it) but otherwise has been rock solid reliable for me.

 

One thing to keep in mind is that the brakes on the 06 CTTS are staggeringly expensive to replace.
And it will also have the "Coolant Pipes & T" issue. 90k isn't too long for them to still be original.

Having said that, I'd still pick the one in better condition, and better records.

 

Well it's not just the PDCC you paying extra for, but a Sport button for quicker throttle response, much lower mileage and better looks ( )

 

Get the 957 with PDCC - it makes the vehicle defy physics for something as large and heavy as it is - obviously not really, but it feels like it. You can also turn the non-S into a TTS with some hardware mods like larger Intercoolers, upgraded Diverter valves, and a tune for a little more boost if you need the addt'l 50 HP.

 

I've got exactly the same combo
you're deciding on and would choose a 955 TTS. PDCC is perfect and everything but there's something about the older looks and power delivery of a non-direct injected engine that I really like

 

I looked and lurked for a long time before I bought my 957. I didn't consider TTS models for the front brake replacement costs. I also prefer the looks of the 957 and for some 500hp isn't enough but, for most, more power is kind of gratuitous. I love the PDCC, super impressive, REALLY livens up the drive in sport mode. Try it

Price gap sounds about right, $20k for a one owner TTS with OK miles. I would hope the tubes and cardan had been done for $20k, along with fresh brakes on that one! $26k for a 64K mile '08 TT is pretty close. I paid ~$25k for one with 68k miles recently.

I voted with my $$ and picked the 957 over less expensive 955s. It is usually best to buy the newest Porsche you can afford. They typically get better and better. No regrets on mine, rides like a dream in comfort, scares the neighbors coming up the canyon in sport.

Good Luck

 

OP is looking at an '08. DFI engine wasn't until '09, which is why I bought my '09 TTS. i also prefer the slightly updated looks of the 957 over both the 955 or 958 and newer.

 

The change to the 4.8 DFI coincided with the release of the 957 in 2008.

And I would go with the 957.

 

Yes TTS front brakes cost more, but they also last a really long time.

Don't the 957's still have the same coolant pipe/T issues the 955's have?

 

Thanks for the info. Thought it paralleled the DFI release in the 997, which was '09 but am more a 997 than a 957 expert at this point, so appreciate the correction.

 

Great info everybody! I really appreciate it, I've never experienced the PDCC but looking toward to it. Let's hope the PPI looks good on the 957, will know Thursday.

 

I agree. Not sure I'd rule out a well maintained ride because of the cost of brakes, I'd just plan on it being a big chunk of change and suck it up when the time came. Kind of like 21" wheels vs 20s, the additional cost of 21s is just something you plan on.

I believe the early 4.8s had a coolant fitting/pipe issue but it's nowhere near as egregious or prevalent as the problem with the 4.5s. At least that's what I got when obsessing over these things before I bought mine.

Pretza, I try not to be "that guy" Still trying to learn a ton of P-car speak myself, this world is WAY different than where I'm from. After doing the first major maintenance on my Cayenne, I will say I'm even more impressed with this vehicle than I was when I first bought it.

 

I don't think so.

They have a redesigned "under the intake" pipe setup that is much more reliable.

They do, however, have the "water distributor" issue, where one of the fittings can pull itself out (or get pushed from the pressure).
Similar, but not the same.

I know the 955 issues intimately, but am not totally up to speed on the 957 stuff (guess which one I own )

 

uphoto, just drive both and get the one that makes your peen harder. Can't go wrong with either unless you choose one with scored cylinders!
