Every generation. Every trim.
Every common failure.

Twenty-five years of 911 buying compressed into one document. From the maligned 996 to the everyday-supercar 992, six generations broken down by trim, year, IMS-vs-DFI, common failures, sweet spots, and what to actually pay. The same research I hand to every client buying a 911.

Sample preview

A real excerpt from Chapter 03.

Below is a section from the 997.2 chapter, specifically, the part that walks you through why this generation is the smart-money pick for most buyers.

Chapter 03 · 997.2 (2009–2012) · pp. 22–24

Why the 997.2 is the smart-money 911.

If you forced me to recommend one 911 generation to a buyer who said "I want a 911 I can drive every weekend, never worry about, and not lose money on", I'd say 997.2 every time. Three reasons.

The first is the engine. Porsche moved from the M96/M97 to the new MA1 direct-injection flat-six for the 2009 model year. That single change retired the IMS bearing question, the bore-scoring fear, and most of the long-tail mechanical anxieties that haunt 996 and 997.1 ownership. The MA1 is, by every objective measure I have, the most reliable Porsche flat-six ever built. That alone moves the 997.2 from "you'd better find a sorted one" to "buy whichever one fits your budget and colour preferences."

"The 997.2 is the most you can pay for the least amount of worry, and that combination doesn't exist anywhere else in the 911 lineage."

The second is the chassis. The 997.2 retained hydraulic power steering, the last 911 to do so. For owners who came up driving 70s and 80s sports cars, that hydraulic feel is non-negotiable; for owners who'll never have driven anything else, you'll lose nothing by picking up an electric-assisted 991, but you also won't gain anything either. Either way, the 997.2 is the last car where the steering is unequivocally a feature, not a system.

The third is the depreciation curve. I've watched 997.2 Carrera S values for ten years now, and they've spent eight of those ten years sitting flat. The bottom isn't going lower; the top isn't going meaningfully higher. You buy one for $78,000 today, drive it for five years, and sell it for $74,000–$80,000 – call it a $4,000 net cost over five years of ownership. That's hard to beat in any car, period, let alone one that holds 400hp and a six-speed.

Engine3.8L MA1 DFI
Power385–408 hp
Annual depr.$800–1,400

What to actually buy: a 2010–2012 Carrera S manual or PDK, with under 80,000 km, full Porsche service history, and ideally Sport Chrono and PASM optioned. Avoid the 2009 model year (one production change adopted later) and any car with a salvage history…

Excerpt continues for another 1.5 pages, including specific options to look for, the 8 PPI red flags for this generation, and a year-by-year price floor analysis. Full content in the PDF.

Honest disclosure

Who this is for ,
and who it isn't.

Buy this if…

  • You're seriously considering buying a 911 in the next 6–12 months.
  • You're trying to decide between two specific generations and need a tiebreaker.
  • You've seen a 911 you like online and want to know what to ask before you fly to see it.
  • You want one document that covers every generation, not six different forum threads.
  • You want my actual research, not a recycled magazine summary.

Skip this if…

  • You're already deep in the 911 community and have your own opinions.
  • You're shopping a different model – see the rest of the Deep Dive series .
  • You'd rather skip the research and have me source one for you (that's Matchmaking ).
  • You're looking for forum-level depth on a single generation – the Bible covers all six in detail, but it's not a 911-only encyclopedia.
FAQ

Common questions.

Does this cover air-cooled 911s (964, 993, etc.)?

No, the Bible covers 996 onward, the modern (water-cooled) era. Air-cooled 911 ownership is a different game with different mechanical considerations and a much older buyer market. I have a separate guide planned for that audience.

Will it tell me which 911 to buy?

It will tell you which 911 fits your situation, with the trade-offs spelled out. There's a "for whom" recommendation at the end of every generation chapter. If you're between 997.2 Carrera S manual and 991.1 Carrera 4S PDK, the Bible will give you a clear-eyed answer for each scenario.

Do values stay current?

The pricing ranges are updated each year. I refresh the document annually (next refresh: Jan 2027) and you'll get the new version free for life as part of the purchase.

Does it cover 911 Turbo and GT models?

Yes, every generation chapter has full Turbo and GT3/GT2 sections. The "Special Models" chapter (Ch. 07) goes deeper on GT3, GT2 RS, 911 R, Speedster, and the current ST.

Refund policy?

7 days, unconditional, no questions. Email david@carsmenskii.com with "refund" in the subject, I process the same business day.

Should I buy this OR the Inspection Checklist?

Both, ideally. The Bible tells you which 911 to buy and what to look for at the model level. The Inspection Checklist tells you what to physically inspect on any car you're considering. They pair, that's why I offer them as separate products. Together it's $68; if you want the bundle, see the bottom of this page.

The flagship Deep Dive

Buy the Bible.
Then buy the right 911.

A 911 is a serious purchase – usually $60,000 minimum, often well into six figures. The $25 to spend a weekend with this document and arrive at a confident, defensible decision is the cheapest insurance you'll buy on the way to ownership.
