Default 2017/2018 Cayenne vs Cayenne S reliability

Hi folks, new to the forums but was hoping to get some feedback from owners in this group.

I am in the market for a 2017-2018 Cayenne. Ideally I'd lilke an S for the extra power but if there was a better condition regular Cayenne at the right price I would be open to that as well.

Based on my budget, I am looking at 2017/2018 models with KM's around 70k - 100k under it's belt (Canadian Market)

Many of these are offered by our local Porsche dealderhip (here in Vancouver) with the 2-year unlimited miles limited warranty coverage (which based on my research is the same regular warranty on new porsches that covered manufacturing defects but not consumables).

I only drive around 10K km / year so to me a higher mileage car isn't a huge issue. Even with a 100K km car I can drive it for another 5 years to 150K km and still have plenty of life left.

Does anybody have experience with these cars with higher KM's on them? Any comment on choosing the V6 over the S model? There are also a few S E-hybrids on the lot too if that makes any difference.

From what I've seen the biggest issue mechanically is the transfer case. I hope at such high KM's the car either 1) has already had it replaced or 2) has come so far without the issue that the issue will not materialize.

Any other issues to worry about? Would a similar condition Macan S be a better bet? Looking for a comfortable semi-weekend cruiser. Will mainly be doing city and slight highway driving a few times a week.

Avoid the hybrids (batteries are expensive). The base VR6 motor is easily the most reliable, but relatively slow for a heavy SUV. Most people are fine with that. The TTV6 in the S model has much more grunt, but also with some increased headaches. Very common head bolt/timing bolt cover leaking issue (now there is an aftermarket bolt set to fix this issue), and rear vacuum pump oil leak (even the 958.1 V8's had this issue). There was also a software update to address a stumble issue. There are many threads of the TTV6, use the search function above to dig through them at your leisure.

Thanks for the feedback. After reading around it does seem like battery failure is a common issue for the hybrids. However it seems like most cases are due to leaks from sunroofs or trunks and such and the rain water seeping into the battery. Having said that, I live in Vancouver where is rains 2/3rd's of the year so maybe the E-hybrid is out.

I do see many listings for models in the 150k km to 170k km range so i'm confident a properly maintained Cayenne can last a while.

I'll do a test drive on the regular V6 to see if I can live with the that amount of HP

Get a S, I’ve had both.

We bought our 2017 958.2 Cayenne S used 2 1/2 years ago with 36000 miles and are now nearing 80000 miles (130000 km). Transfer case was replaced before we got it at about 32000 miles. Aside from needing the software update, we've had no major issues since owning it. My wife daily-drives it to work, we've taken a number of road trips in it, and I use it frequently to tow my race car to/from the track (up to 5 hour drive, depending on where we're going).

Only complaint: I wish we would have had the rear AC in ours. AC into the back seat area isn't particularly good. The way the transmission is tuned, the car feels a bit more sluggish than I would expect given the amount of available horsepower on tap. In Sport mode it accelerates about how I would expect, but the downshifts during deceleration are a bit too abrupt for my liking. You can get an extra 100+ hp and torque with a Softronic tune. I've been considering pulling the trigger on that, but really wish I could give one a try and see how it behaves.
