Porsche 997 911

Buyer's Guide

Porsche 997 911

2004–2012

Overview

The 997 is the 911 I'd recommend to most people: modern enough to use every day, traditional enough to still feel like a 911. The 2009 update (997.2) brought direct injection, PDK, and an engine without the intermediate shaft bearing, and it's the safer buy. A 997.1 with a clean bore scope and IMS paperwork is still a great car for less money. The GT3s, and the 997.1 Turbo, use the Mezger engine and live in their own market.

Which One to Buy

Carrera / Carrera S (997.1)

2005–2008

The first generation, with a 3.6L (325 hp) or 3.8L (355 hp). It still has an IMS bearing, though a stronger design than the 996's. The S is the one I'd buy.

Desirability Medium

Carrera / Carrera S (997.2)

2009–2012

The second generation, with direct injection: 3.6L (345 hp) or 3.8L (385 hp), no IMS bearing, and the PDK as an option. The safer buy.

Desirability High

Carrera 4 / Carrera 4S

2005–2012

All-wheel drive, with the wider rear body. More planted in all conditions.

Desirability High

GT3 / GT3 RS

2007–2012

The track-focused GT3s, with the Mezger engine making 415–500 hp and no IMS bearing. The RS adds aero and loses weight. Highly collectible.

Desirability High

Turbo / Turbo S

2007–2012

Twin-turbo, 480–530 hp, and all-wheel drive. The 997.1 uses the Mezger engine; the 997.2 moved to a new direct-injected engine.

Desirability High

GT2 / GT2 RS

2008–2012

The rear-drive Turbo, with 530–620 hp. The most extreme 997, and the GT2 RS is one of the wildest 911s ever made.

Desirability High

Walk Away If…

  • 997.1 with unknown IMS status or bore scoring symptoms
  • Check engine light with multiple codes
  • PCCB brakes with visible damage or wear
  • PDK with shudder or rough engagement
  • Salvage title without clear documentation
  • GT3/RS with track damage or unknown racing history

Pre-Purchase Inspection

What I'd check on any 997 before buying, with a rough cost if it's bad. Print it and take it with you.

Engine (997.1 IMS) 3 checks
  • IMS Bearing Status (997.1 only) 997.1 still has IMS bearing but improved design. Failure is less common but still possible. Check if retrofitted. If bad: $2,500–4,000 for retrofit
  • Bore Scoring (997.1) M97 engine can develop cylinder bore scoring. Check for knocking, smoke, or oil consumption. If bad: $15,000–25,000
  • D-Chunk Failure (997.1) Early 997.1 engines can suffer from crankcase cooling duct failure. If bad: Engine replacement if severe
Engine (997.2 DFI) 3 checks
  • Carbon Buildup DFI engines can develop intake valve carbon buildup. May need walnut blasting at high mileage. If bad: $500–1,000
  • Direct Injector Condition DFI injectors can fail causing rough running. Usually diagnosed with scan tool. If bad: $800–1,500
  • Oil Consumption Some oil consumption is normal. Monitor level between services. If bad: Monitor and maintain
Transmission 3 checks
  • Manual Transmission Test every gear. The six-speed manual is tough and well liked. If bad: $2,000–4,000
  • PDK (997.2) Check for smooth operation and proper clutch wear. PDK requires fluid service. If bad: $1,500–5,000
  • Clutch Manual car clutch engagement should be smooth. Dual-mass flywheel is expensive. If bad: $3,000–5,000
Suspension & Brakes 3 checks
  • PASM Shocks If equipped, test in all modes. Shocks can develop leaks. If bad: $2,000–4,000
  • Control Arm Bushings Check for clunking and worn bushings. Common wear item. If bad: $600–1,500
  • PCCB Brakes (if equipped) Ceramic brakes are expensive to replace. Check rotor condition. If bad: $10,000–20,000 for replacement
Electrical & Interior 3 checks
  • PCM/Navigation Check touchscreen function and navigation. Older units may need updates. If bad: $500–2,000
  • Convertible Top (Cab) Test full operation including automatic wind blocker if equipped. If bad: $1,000–3,000
  • Sport Seat Bolsters Driver side bolster wear is common on sport seats. If bad: $500–1,500

Worth Paying Extra For

  • 997.2 for best reliability (no IMS concerns)
  • Carrera S or 4S for best all-around package
  • Manual transmission (purist choice) or PDK (faster, easier)
  • Complete service documentation
  • Sport Chrono Package
  • PASM adaptive suspension
  • GT3 for track use (Mezger engine, no IMS)
  • Lower mileage with consistent service history
