2015 C7 Z06 Convertible Z51pkg (stiffer springs) Magnetic Ride Suspension, which was quite good, LT3pkg (spoilers & carbon - amp’d up interior) heres how 83,000miles (street only - highways/backroads 20/80%) in 5yrs looks from an "in the shop" perspective

Ordered Dec. 2014 - when I took myself off a wait list for GT3-RS due to No Drive Order issued by Porsche for the first 400 cars delivered due to fires - they replaced the engines - I switched camps to GM - car arrived April 2015:

3 Flex plates -1st one @ 2400 miles, 2nd @ 3600 miles - requires transmission & drivetrain removal
1 Torque Converter
1 Rear Differential (complete)
2 Valve Springs (broken) - 1 @38k the other @ 65k miles
3 Service Rear Axle "issues" - plagued me from 10,000miles to the very end but 3 visits were serviceable and the service message disappeared for a while
3 StabilTrac Issues - bad solenoid on rear differential - the whole differential was replaced initially but eventually the same issue reoccurred
StabilTrac applies brake as needed - in my case it applied it/them even when not ! Very unnerving - might as well head back to service instead of enjoying a ride
4 wheels - repurchased out of pocket - cracked/dented - known GM wheel issue as being very delicate but who can really say...roads aren’t perfect either
6 sets of Cup-2’s — These were fun !

1 SuperCharger - making noise - replaced
Service Brakes On DIC (Drivers Info Center) that started at 25,000 miles & never went away - possibly a sensor wire worn - never repaired
Excessive Oil Consumption - Compression Test showed normal
Oil usage when on/off throttle/spirited driving, is approximately 1 quart every drive of 300+ miles (I’ll usually do that on a day drive)

After a total of 83,000miles it’s over - right up to the end it was still giving me issues that the service dept just got tired of it too

I now have a 2021 TTS Cab that has taken its place - from the very start of turning the key @ the dealership, & the drive home....you can tell the day by its dawn

It would be interesting if someone has a Porsche 5yr ownership "service report" of ownership issues - other than the smiley faces

How would a Porsche (of similar spec/the closest one) match up ?

 

Not a corvette, but had a brand new Escalade (another GM 'top of the shelf product'), and had nothing but issues with the car.... Switched it for a new Range Rover (go figure) and had 0 issues.

 

I have a 2014 TTS in the close to 7 years of its life it has never been to the dealer or Indy for anything other than normal maintenance or Porsche recall minor items. Even tuned, with after market exhaust it is an Ever Ready Bunny that just keeps on going and quickly.

 

Threads like this are ridiculous.

We should not need to disparage another brand in order to make ourselves feel better about our 992 911

 

I agree.

I am also on another board for a marque that also includes a prancing horse, and those guys look down on Porsche owners the same way that some of the posters here look down on Corvettes.

Much the same way that many Corvette owners look down on Mustang/Camaro owners.

It's petty, and a real psychological tell

 

if GM didn’t push out such ****ty quality products and service, we wouldn’t even be talking. It’s disrespectful to a company like Porsche whom is so passionate and obsessed about engineering and cars to compare them to a company like GM comprised of bean counters and lawyers that gives more time doing cost/benefit analysis into cost of wrongful death lawsuits from garbage ignition switch failures than to actually getting it right the first time with a switch that would have cost them an additional $.03 per unit.

 

^ Not a fitting comparison. Those Ferrari owners who are doing that are just snobs. But I'd rather own a 911 than a Ferrari, frankly speaking. I'd enjoy a Ferrari for about a month and be desperate to give it back.

Nobody here is disparaging Corvette owners. It's about the difference in quality of the built product between GM and Porsche, essentially.

 

I had my 458 for 2 years, and my 488 for 3 years - loved those 5 years, and even more loved the cars.. a driving experience! But I did 3,000 miles in 3 years withe 488, and 1k in 1 month in the 992 TTS.... Different car, for different missions. I 100% completely agree that this is not about Corvette owners, but about build quality. I.e. The Ferrari has a better build quality than the 911.

 

I went through 3 engines in 103000 miles in C6 Corvette. The last one was not under warranty. Gave it to a friend. Bought a 2011 Carrera which now has 110000 miles and recently had first problem being the tpms. Minor but can’t be fixed. One service on PDK and plugs at 85k and brake bleed sole service! And it makes the Vette seem more like a sedan in comparison. But the Chevy dealership could not have been better. Porsche dealership experience maybe is better but not really as only 2 dealerships in Oregon.

 

I like all of them, so no disrespect....the build quality for me, would only show itself after the miles start accumulating, I buy them to drive them & take care of them as an enthusiast, not for the next guy to own (meaning to sell a low milage car) if there are higher mileage cars (8/10/12k a year - just ingress egress for most of the exotics has them sitting in the garage) that do not need more than standard service I’d say that means something to me for build quality...I know a few owners, and that kind of mileage just isn’t happening - the dealer themselves will say: "after 3000miles a year you’re putting too many miles on" - granted they are (probably) talking resale value for them as a dealer - without a doubt (for me - and I’m new to the Porsche world) the Porsche is the drivers car, the Ferrari is for lovers —— "I bought the Porsche with my brain, the Ferrari with my heart"

 

2020 C8 and 2020 911 C4S. Both mine and each has it's own special personality and I really like them both. The performance is nearly identical. Long term I'm not sure. Still have my eye on that 2021 911 TTS.

 

give me a huge break. Porsche, for all its renowned engineering process, has built some total dog**** motors for many years. Ims, bore scoring, chunking cylinders, cracking heads, 993 valve guides, magnesium cases, cracking head studs, SC tensioners, GT3 followers, etc.

If you don't think porsche would conduct the same bean counting, you're mental.

Let me put it this way, I'd much rather have a GM V8 than any non-mezger porsche engine made from 97-2008.

 

Have had a few Corvettes in the past - C5 and C6s. When they went to the C7 I lost interest due to the styling - trying to go too exotic for my taste. C8 goes even further. Have lost their "iconic" look to me, which I much prefer and is what makes me love the 911. Never had an issue with the performance or reliability of my Vettes, but don't have any real insights on latest versions.

 

You seriously gonna rag on 85 year old men? You will be lucky to live that long let alone still driving to a dealership. Any 85 year old doing that is Based!

 

I’m gonna sit on my front porch, drink PBRs and whittle wood with my trusty golden retriever by my side if I make it to 85.
