Used Porsche 911 type 991: strengths, inspection points and market context

The 991 combines strong dynamics, precise steering, high build quality and surprising long-distance ability. Before comparing prices, confirm whether the exact car is a 991.1 or 991.2, its Carrera variant, coupé/cabriolet/Targa body, PDK or manual gearbox, drivetrain, equipment and specialist history.

This guide covers the German-market Porsche 911 type 991 from 2011–2019 as Carrera, Carrera S, Carrera 4/4S or Targa with a petrol engine. It separates the 991.1 and 991.2 and excludes the 997, 992, Turbo, GT, R and other special models. The type, engine, body, drivetrain, gearbox and production date need to be confirmed for the individual vehicle.

Before the viewing, clarify these points: 1. Identify type 991, 991.1 or 991.2, Carrera variant, body, drivetrain and gearbox exactly. 2. Review Porsche/specialist invoices, servicing and mileage trail chronologically. 3. Clarify VIN recall status, over-rev/diagnostic report, track, accident and modification history before viewing.

If you already have one concrete listing, a Listing Audit can help sort the visible information, missing evidence, and next seller questions before you travel.

ADAC describes the 991 as a very reliable, well-built sports-car icon with excellent steering, powerful brakes, comfortable seats and surprising long-distance ability. The boot is small and the rear seats have limited use. At the facelift, Carrera models moved from naturally aspirated engines to a 3.0-litre twin-turbo, so the engine, sound, power delivery and technology differ materially.

ADAC says the 991 performs particularly well in the TÜV report. Registration volume is too low for a robust place in ADAC's breakdown ranking, however, and more than half of the recorded breakdowns involved starter batteries. Battery condition, tyre age, brakes and storage history therefore belong in the individual assessment, especially for seasonal or lightly used cars.

Our editorial view: despite strong series-level results, a 991 needs Porsche-capable diagnostics, a specialist inspection and a traceable history. Carrera, S, all-wheel drive, Targa, cabriolet, PDK, manual gearbox and options affect use and running costs. Vehilo did not road-test a 991 for this article; this is not an in-house driving review.

FAQ snapshot on 5 September 2026: AutoScout24's Porsche 991 category reported about 450 offers and 43 new listings in the previous seven days. The median asking price was €120,868 and the middle 50% ran from €96,877 to €153,754. Dealers accounted for 81% of adverts and private sellers for 19%.

The page showed 252 coupés, 193 cabriolets and 406 automatics or 90%. The stock includes the 991.1 and 991.2 as well as Carrera, Turbo, GT and special models; body, drivetrain, engine, gearbox, year, mileage, history and condition are mixed. The price measures are therefore not tailored to the Carrera family covered here.

Our market view: 450 offers indicate an active but highly varied asking market. The 43 newly posted adverts are not a sales figure. These are asking prices and advertised stock, not completed sales, transaction prices or ownership transfers, not a valuation, and not a value, trend or resale forecast.

KBA reference 6738, Porsche code AH01, was published on 24 March 2017 for 718 and 911 production from 2015–2016. A leaking fuel line may release fuel in the engine bay. The remedy replaces the fastening screws; the CSV's possible restriction includes 911 Carrera and Targa.

The CSV lists 16,429 potentially affected vehicle parts and accessories worldwide and 2,570 in Germany. Known incidents are recorded as “N/A”, which is not a zero-incident claim. The campaign is marked “überwacht” (monitored), which does not establish completion on an individual car.

The row does not identify type 991, engine, body, drivetrain, gearbox or an individual VIN. Its period and Carrera/Targa restriction overlap this guide, but prove neither that every 991 is affected nor the status of a specific car. One row is also not a complete 991 recall list. Check the VIN through Porsche's official recall portal or a Porsche Centre and request written completion evidence.

The main inspection areas are: 1. Starter battery and storage time as an ADAC breakdown focus 2. 991.1 naturally aspirated or 991.2 twin-turbo engine, PDK/manual and documented maintenance 3. Brakes, tyres, chassis, cooling and possible track use 4. Accident history, paint finish, underside, modifications and original parts

Our view: ADAC rates the technology, build, handling and roadworthiness results very highly, while noting low sample volume in its breakdown statistics and battery trouble on lightly used cars. The AutoScout24 snapshot mixes Carrera, Turbo, GT, body styles and production phases and is not a valuation. The KBA row is a recall lead, not a complete recall history or VIN clearance.

Questions for the seller: 1. Which Porsche/specialist invoices and digital service entries are available? 2. Is there a current over-rev/diagnostic report and evidence for PDK or clutch work? 3. Any track days, accident damage, repainting or performance modifications? 4. Which original parts, keys, documents and recall evidence are present?

Inspection priorities on site: 1. Plan Porsche-capable diagnostics with over-rev data and an independent specialist inspection. 2. Have the engine, cooling, PDK or clutch assessed professionally cold and warm. 3. Check paint depth, underside, suspension, brakes, tyre age and even wear. 4. Reconcile equipment, mileage trail, servicing, damage, modifications and recall evidence.

Slow down when these signals appear: 1. 991.1/991.2, engine, gearbox or equipment remains unclear. 2. Porsche/specialist history or mileage trail has unexplained gaps. 3. Diagnostics, track use, damage or modifications remain vague. 4. The seller will not allow a Porsche-capable inspection or VIN check.

Is a higher-mileage 991 automatically problematic?

No. Chronological servicing, use, diagnostics, wear items and a specialist assessment are more informative than mileage alone.

Are 43 new listings in seven days sales figures?

No. AutoScout24 describes newly posted adverts and current asking stock, not completed sales, transaction prices or ownership transfers.

Does KBA 6738 automatically apply to every 991?

No. The row names 911 Carrera/Targa production from 2015–2016, but not type 991 or an individual VIN. Only Porsche's VIN check and completion evidence resolve the specific car.

The evidence tiers separate authority or manufacturer sources from buyer guides and owner-reported patterns. Reddit, YouTube, and forums help discover questions for research, but they are not used as standalone proof for public defect claims.

This article is buyer guidance, not a technical diagnosis, workshop inspection, guarantee, legal advice, or proof that a specific car has a fault. Model notes are inspection prompts. A specific car still needs history, condition, recall status, and qualified inspection context.
