Lot 3273: 2006 Porsche 911 Carrera S

Great question! The 2006 Porsche 911 Carrera S (997.1) is a fantastic car, but like many sports cars of this era, there are a few well-documented mechanical concerns you should know about:

🔧 The Two Big Ones (Engine)

1. IMS Bearing Failure This is the infamous “Intermediate Shaft” bearing issue that affects 1997–2008 Porsche 911s. If this bearing fails, it can cause catastrophic engine damage. The 2005–2006 Carrera S models seem particularly vulnerable according to owner forums. The good news: many enthusiasts have this addressed proactively with an IMS Retrofit Kit (~$2,500–$5,000), or you can check if it’s already been done on a specific car.

2. Cylinder Bore Scoring More common in the 3.8L Carrera S engine (vs. the 3.6L base Carrera). This causes excessive oil consumption, rough idle, and potential engine knock. At 31,000 miles, a well-maintained example like the one we’re looking at may have dodged this bullet, but it’s worth monitoring oil levels closely.

💧 Oil Leaks

Rear Main Seal (RMS) Leaks A chronic issue where the seal between the engine and transmission leaks oil. Porsche redesigned this seal multiple times, but it never quite went away. It’s not catastrophic—just messy and worth fixing before it gets worse.

🛻 Convertible-Specific Issues

Since this is a Cabriolet (like the one in our listing), hydraulic top problems are common:

• Slow or stuck convertible tops
• Failed lift supports (the struts that push the top up)
• Hydraulic fluid leaks in the system

These typically crop up after 10+ years as seals age, so budget for potential hydraulic cylinder rebuilds (~$800–$1,500).

⚖️ The Bottom Line

With just ~31,000 miles, this particular Carrera S is relatively low-mileage for its age, which helps—but I’d definitely verify if the IMS bearing has been addressed and look for any service records. Most enthusiast buyers consider the IMS service non-negotiable on these cars.

Our market data shows these manual Cabriolets typically average around $46K, so this one’s asking price of $74,995 suggests a premium, well-maintained example—worth confirming the IMS status and bore condition before pulling the trigger!
