Yup and did.....and haven't looked back since!

With today's synthetics, every single fact (almost) of conventional oils regarding lifecycle, hygroscopicness, turning to acid, etc... it all goes out the window or is drastically different.

Get a good pre purchase inspection, change the fluids for peace of mind, let the rest eat, drive the **** out of it, and enjoy the car to the fullest. It's not a precious metal, and it's definitely not an 80's GM car.

Thank you everyone. It seems I am going to pull the trigger, even though still have my doubts. The way it looks, I will have to spend at least $7-8k to do the following:
- Tires are still the original tires. Definitely need new tires.
- PDK service is due
- New Coolant, brake fluids, engine oil
- All belts
- Spark plugs (and coils?)
-Air Filters
Did I miss anything?

I will post pictures and built sheet shortly. Going to get the car most likely on Saturday.

$75k Base PDK 911 but with decent amount of options.

Depends. Where was it stored, somewhere dry or in a damp garage? Was it parked in a garage or outside?

I bought mine from the original owner when it was just over 3 years old and it had 98 miles. I did get all the records from the day he took possession at the dealer.

Fluids are a no brainer if you are mechanically inclined. Maybe tires (once again, depends how it was stored). I still have the original tires that are now 9 years old but with low miles. I have no issues pulling Gs.

What kind of boat and engine. My Mercruisers would never withstand that.

Do a major service - $2,200 last time I did one.
New Tires all around - $2,136 for Michelin 4S

and you are done. No way it's $7-8K unless they find something serious. I have a 17 991 with about 5K on it and a GT3 with less than 1K on it. Zero problems. That said I do an annual service every year and roughly follow the "time" service recommendations. For example I did the major service at 4K miles vs 40K because the car was 5 years old.

As a side note I ran a set of tires on my Turbo for 10 years before I replaced them. Low milage garage queen and did not track it. It was fine but they were rock hard; after putting on the new set it was like driving a different car. I have the original tires for my 85 Esprit with 4K miles on it. They are fine for street use but also rock hard. The point is unless you are going to track the car you could run with the stock tires for a while.

I continue to chuckle at the oil change thing - if the car is driven, say, 500 miles a year, and the oil isn't EVER changed - over 10 years, it likely won't matter one whit. Now, it COULD matter, but not likely - as noted the worst circumstance would be for the engine to run for 3 minutes and then be shut down - best with that mileage would be an owner who took the car out on nice days for an hour drive. How much particulate material would be in the oil from just sitting there - not much. How much gasoline thinning based on the mileage - not much. Assuming the degradation of he actual oil is limited (or is it - lack of data) - would love to see a curve for even basic Mobil 1 Euro spec.

This is NOT 1950, and agree the oil is NOT intelligent (I enjoyed that post!) - it is synthetic - how long would be it be viable? Hmmmm ... imagine it sitting for 50 years in a barn in Minnesota ... would it still be oil? Would it really change much, at all? How about in a shed in Venezuela ... would it change much? I haven't found analysis of this circumstance - most online material is drivel from manufacturers or sellers of oil changes (suspect).

I love car opportunities like this - get it PPI'd by an indie shop, then have same shop do the stuff needed ...

abso-freaking-lutely. After a PPI.

I just about did that. I bought a 9 year old C2S with 13k miles. Spoke with the PO on here and ended up purchasing the car from a dealer near me. I had a major service done on it a few days ago and the car has been fantastic for the 550 miles I’ve put on it so far. I wouldn’t hesitate to do it again.

Kubotarog

Bought a one owner 2014 991.1S CPO a year ago. 12k miles and up to date, time wise on all service. Changed the oil in January at 14,500 miles. Will do time and mileage based services going forward. Car has been mechanically perfect. Did have a headliner sag which dealer replaced. My advice, do it and don’t overthink.

HardRider

Mercruiser 3.0 liter. Sterndrive. Abuse was off the scale. I didn't want my cars wheels wet so as soon as I started engine full throttle reverse to get off trailer. It had a 140F thermostat, this prevents salt precipitation in cooling system. Went through exhaust manifold every 10 years. They always failed backside of exhaust passage where hot exhaust gas was on one side and water on the other. Original outdrive. Had points and condenser. Over life of boat we had 1 dislocated shoulder, 2 cracked vertebrae, 3 pinched nerves, over 15K beers consumed and again I sold 4 years ago. Lived entire life in Galveston bay. Was flushed after each use.


The aforementioned emphasis the ridiculous money grab Porshe does to innocent owners......... I changed my 911 oil last year, it came out so clean I used it in my daily beater Lexus with 220K miles which doesn't use drop. Much faster with that Porshe oil now..... Oil change interval is 10K miles.....

Looks like you are getting a shop to do the work.

I would not waste my money replacing coils simply because there is no "best before date" on them. The original 9 year old coil sticks on my low mileage (same mileage like yours) 991.1 are fine. On the PPI, I'd have them replace the plugs, although I had absolutely no issues removing them on my car at year 7.

Bud Taylor

and then get them to agree to service (after you have the result from PPI, not before)

Tires 2400
PDK service (not sure $400) ??
Coolant Brake Fluids engine oil (500)
Plugs/Coils ($600)
Belts - I would inspect not replace. Their lifespan is revolutions not time. I would not actually muck about with the coolant for a couple years either.

Looks like 4K to me but if you are going to deal with crooks at the dealership then its Las Vegas land. By the way I would add in brake fluid to the mix. The oil to change in this car is stupid easy and in no way requires an expert. Get 10L of Xcess Gen2. The plugs and coils could also be done by a chevy mechanic.

The advice I heard and plan to follow with my low mileage 991 that I bought: Perform the service based on the age of the car and not the mileage.

I.e. get the 80k service (or equivalent) at the 8-10 year mark regardless of the cars mileage. And I'm not saying it has to be service performed by the dealer, I have no problem with equivalent service from an indie or even DIY if you are so inclined.

I'm sure there will be exceptions to this though so use your best judgement.
