Buying a used Porsche Cayman is a dream for many sports car lovers. The Cayman is famous for its sharp handling, mid-engine balance, and daily usability. But not every year is equally reliable or trouble-free. Some Cayman years are best avoided if you want to save money, avoid headaches, and get the most joy from your Porsche experience. In this article, you’ll learn which Porsche Cayman years to avoid, why they have problems, and what you should look for when shopping. We’ll also compare different Cayman generations, offer real-world examples, and answer common questions to help you buy with confidence.
Why Some Porsche Cayman Years Are Risky
Not all Cayman models are built the same. Porsche is known for constant improvement, but some years were affected by design flaws, poor materials, or engine issues. These problems often don’t show up until cars are out of warranty, leaving owners with expensive repairs.
Knowing which years are problematic helps you avoid hidden costs and enjoy the legendary Porsche driving experience.
Common Problem Areas
- Engine failures: Some years had serious issues that could destroy the engine.
- Intermediate Shaft (IMS) bearing: This small part caused big problems in early Caymans.
- Bore scoring: Cylinder wall damage leading to oil burning and engine failure.
- Electronics and interior quality: Certain years had more electrical glitches or cheap-feeling interiors.
Many buyers only look at price and mileage. But experienced owners know that a bargain Cayman from a bad year can end up costing much more than a well-chosen model from a better year.
Overview Of Porsche Cayman Generations
Before diving into the years to avoid, it’s helpful to understand the Cayman’s evolution. Here’s a quick overview:
| Generation | Years | Engine | Major Changes |
|---|---|---|---|
| 987.1 | 2006–2008 | 2.7L & 3.4L Flat-6 (M96/M97) | First Cayman, IMS & bore scoring risks |
| 987.2 | 2009–2012 | 2.9L & 3.4L Flat-6 (MA1) | New engine, IMS issue fixed |
| 981 | 2013–2016 | 2.7L & 3.4L Flat-6 (MA1) | Lighter, improved interior, reliable engines |
| 718 (982) | 2017–present | 2.0L & 2.5L Turbo Flat-4 / 4.0L Flat-6 (GTS/GT4) | Turbo engines, mixed fan opinions |
Porsche Cayman Years To Avoid
Some Cayman years are famous for expensive engine problems and other headaches. Here are the main years most experts and owners say to avoid:
1. 2006–2008 Cayman (987.1)
The first-generation Cayman (987.1) looks great and is fun to drive, but these years have two major risks: IMS bearing failures and bore scoring.
Ims Bearing Failure
The Intermediate Shaft (IMS) bearing is a weak point in early Porsche flat-six engines. If this bearing fails, the engine can be destroyed in seconds. While not every Cayman will have this problem, the risk is real and repairs are costly.
- What is the IMS bearing? It supports the intermediate shaft in the engine, which drives the camshafts.
- Failure rate: Estimated between 1% and 8% for this generation. Rare, but catastrophic.
- Fix: IMS bearing upgrades are possible, but not cheap.
Bore Scoring
Bore scoring means the cylinder walls get scratched, causing oil burning, smoke, and eventually engine failure. This is especially common in the 3. 4L S models.
- Symptoms: Ticking noise, increased oil use, smoke at startup.
- Repair cost: Often $10,000 or more for a full engine rebuild or replacement.
Real-world Example
Many buyers report spending as much as $15,000 on repairs after buying a “cheap” 2007 Cayman S. One owner noticed blue smoke and ticking after just 20,000 miles. A specialist confirmed bore scoring, and the repair cost nearly as much as the car itself.
2. Early 2009 Cayman (987.2)
Porsche updated the engine for 2009, removing the IMS bearing issue. However, early 2009 models sometimes had teething problems with the new Direct Fuel Injection (DFI) system and electronics.
- Issues: Misfires, faulty sensors, and rare but expensive DFI injector failures.
- Improvement: Most 2010 and later cars are much more reliable.
3. 718 Cayman (2017–2018)
The 718 generation switched from a flat-six to a four-cylinder turbo engine. While most problems are minor, the first two years had some growing pains.
- Turbo oil leaks: Early turbocharged engines developed oil leaks at the turbo seals.
- Turbo lag and flat spots: Some owners disliked the engine response compared to older six-cylinder models.
- Oil dilution: Short trips can cause fuel to mix with oil, requiring more frequent oil changes.
Not A Deal-breaker For All
These issues are less serious than engine failures, but can lead to expensive repairs if ignored. Later 718s (2019+) improved these problems.
Years That Are Generally Safe
Not every Cayman is a risk. Some years are famous for reliability and driving pleasure.
- 2009–2012 Cayman (987.2): The new MA1 engine solved the IMS issue. Bore scoring is very rare. Electronics are improved.
- 2013–2016 Cayman (981): Considered the most reliable Cayman. Great interior, handling, and no major engine problems.
- 2019+ 718 Cayman: Most early issues fixed. Turbo engines have proven reliable if maintained.
Buying from these years is usually a smart choice, especially if you want to avoid big repair bills.

Cayman Problem Areas By Year
To make it easier to compare, here’s a summary of which Cayman years have the most common problems:
| Model Year | IMS Bearing Risk | Bore Scoring Risk | Other Issues |
|---|---|---|---|
| 2006–2008 | High | High | Interior plastics, water leaks |
| 2009 (early) | Low | Low | DFI issues, sensors |
| 2010–2012 | None | Very low | Minor electronics |
| 2013–2016 | None | Very low | Minor issues |
| 2017–2018 | None | None | Turbo leaks, oil dilution |
| 2019+ | None | None | Very minor |
What Makes Certain Years Worse Than Others?
Porsche’s engineering is usually excellent, but the Cayman’s early years were a learning process. Here’s why some years are less desirable:
Poor Engine Design Choices
The IMS bearing was a cost-saving measure that worked well in theory, but not in the real world. It was used on the 987.1 Cayman and other Porsche models from the same era. Once Porsche switched to the MA1 engine in 2009, this problem disappeared.
Costly Materials And Shortcuts
Early Caymans used cheaper interior materials that wear out quickly. Sticky buttons, peeling plastics, and rattling trim are common complaints in 2006–2008 models. While not as serious as engine failure, these problems affect the car’s value and driving pleasure.
Rushed Technology
The switch to turbocharged engines in the 718 Cayman brought more power and efficiency. But early 718s had turbo oil leak issues and some owners missed the sound and feel of the old flat-six. Porsche listened to feedback and improved the car in later years.
How To Spot A Risky Cayman
Just because a Cayman is from a risky year doesn’t mean it will break. Proper maintenance, careful owners, and preventive upgrades can make a big difference. Here’s how to spot warning signs:
- Check service history. Look for regular oil changes, IMS bearing upgrades, and bore scoring inspections.
- Listen for engine noises. Ticking, knocking, or smoke from the exhaust are red flags.
- Look for leaks. Oil or coolant leaks under the car suggest expensive repairs.
- Ask for an inspection. A pre-purchase inspection (PPI) by a Porsche specialist is essential, especially for 2006–2008 cars.
- Test electronics. Make sure all buttons, windows, and lights work properly.
Many buyers skip the PPI to save money, but experts say this is a big mistake. It’s much cheaper to pay for an inspection than an engine rebuild.
Real Maintenance Costs By Year
Porsche parts and labor are not cheap. Here’s a quick look at what you might pay for common repairs by year:
| Year/Generation | IMS Replacement | Bore Scoring Repair | Annual Maintenance |
|---|---|---|---|
| 2006–2008 (987.1) | $2,000–$3,500 | $10,000–$15,000 | $1,200–$2,500 |
| 2009–2012 (987.2) | Not needed | Rarely needed | $1,000–$2,000 |
| 2013–2016 (981) | Not needed | Very rare | $900–$1,800 |
| 2017–2018 (718) | Not needed | None | $900–$1,700 |
Insight: Even a “bargain” Cayman from a risky year can become more expensive than a newer, safer model if major repairs are needed.
Key Signs A Cayman Was Well-maintained
A used Cayman that has been loved and cared for will drive better and last longer, even if it’s from a risky year. Here’s what to look for:
- Complete service records: Prove the car was regularly maintained.
- IMS upgrade paperwork: Shows the risky bearing was replaced with a better part.
- No engine noises or smoke: A healthy engine is quiet and clean.
- Smooth shifting and tight handling: Worn suspension or transmission parts make the car feel sloppy.
- Clean, undamaged interior: Shows the owner took pride in the car.
Experienced buyers know that maintenance history is often more important than mileage alone.
Should You Ever Buy A Risky Year?
It’s tempting to buy a 2006–2008 Cayman at a low price. Sometimes these cars are reliable if they’ve had all the right upgrades and have been carefully maintained. However, you should only consider it if:
- You get a full pre-purchase inspection
- The IMS bearing has already been replaced
- There are no signs of bore scoring or engine damage
- You budget for possible repairs
For most buyers, it’s safer and less stressful to focus on the 2009 and newer Caymans.
Porsche Cayman Generations Compared
To help you choose, here’s a side-by-side comparison of the main Cayman generations:
| Generation | Engine | Reliability | Driving Experience | Best Years |
|---|---|---|---|---|
| 987.1 (2006–2008) | 2.7L/3.4L Flat-6 | Risky (IMS, bore scoring) | Engaging, raw | None unless upgraded |
| 987.2 (2009–2012) | 2.9L/3.4L Flat-6 | Very good | Balanced, refined | 2010–2012 |
| 981 (2013–2016) | 2.7L/3.4L Flat-6 | Excellent | Modern, sporty | All years |
| 718 (2017+) | 2.0L/2.5L Turbo Flat-4 4.0L Flat-6 (GTS/GT4) |
Good after 2018 | Fast, efficient, less sound | 2019+ |
Lesser-known Cayman Buyer Insights
Most articles mention engine issues, but there are a few less obvious things new buyers often miss:
1. Porsche Option Codes Matter
Many Caymans have expensive factory options like PASM suspension, Sport Chrono, or LSD (limited-slip differential). These add value and improve the drive, but not all used cars have them. Ask for the option code list (build sheet) before buying.
2. Not All Maintenance Is Equal
Dealer service is good, but some independent Porsche specialists are even better. They know the Cayman’s weak points and can spot problems early. Try to find a car serviced by a known specialist with Porsche experience.
3. Tires And Alignment Are Critical
Because the Cayman is mid-engined, tire quality and alignment affect handling more than in most cars. Worn or cheap tires make the car feel less stable and hide suspension issues.
4. Early 718s May Drop In Value Faster
The four-cylinder turbo engine in the 718 is not as loved by Porsche fans. Some 2017–2018 cars have dropped in value faster than expected. This means you can get a good deal, but also means resale value may not be as strong as the 981 models.
What To Do If You Already Own A Risky Year
If you own or are considering a 2006–2008 Cayman, not all hope is lost. Here’s how to minimize risk:
- IMS upgrade: If not already done, get the IMS bearing upgraded by a Porsche specialist.
- Regular oil analysis: Change oil often and check for metal particles. Early detection of engine wear can save thousands.
- Listen and watch: Pay attention to new noises, leaks, or smoke. Fix small problems before they become big ones.
- Drive it often: Caymans like to be driven. Long periods of storage can cause seals and gaskets to dry out, leading to leaks.
- Stay on top of recalls: Check with your dealer for any outstanding recalls or software updates.
Porsche Specialist Or Dealer: Which Is Better?
Both Porsche dealers and independent specialists have their pros and cons.
- Dealers: Use official parts, full access to Porsche records, but usually more expensive.
- Specialists: Often more experienced with older models, lower labor costs, can offer upgrades and custom services.
For older Caymans, a respected independent Porsche shop can often offer better value and more personalized care.

How To Find A Good Used Cayman
If you’ve decided on a safe year, here’s how to make sure you’re getting a good car:
- Research the seller: Private party cars with full records are often better maintained than dealer trade-ins.
- Ask for receipts: Maintenance records should show oil changes every 5,000–7,000 miles and all major services.
- Get a PPI: Pre-purchase inspection is a must. Walk away from any seller who refuses.
- Check for accident history: Run the VIN through a service like Carfax. Even minor crashes can affect value.
- Test drive: The Cayman should feel tight, responsive, and make no strange noises.
Insurance And Ownership Costs
Porsche Caymans are not as expensive to insure as some expect, but costs vary by year, model, and driver history. Older, riskier years may cost more to insure because of their history of engine issues.
- Average insurance cost: $900–$2,500 per year depending on location and driving record.
- Parts availability: Good for all years, but 987.1 engine parts are getting more expensive.
- Depreciation: 981 models hold value well; 718 models vary.

Environmental And Daily Driving Considerations
If you plan to use your Cayman as a daily car, newer models offer better comfort, fuel economy, and technology. The 718 is especially efficient, but lacks the classic flat-six sound. Older models may require more frequent repairs and don’t always have features like Bluetooth or modern navigation.
When Is The Best Time To Buy?
Porsche values can be seasonal. Prices often dip in winter when fewer people shop for sports cars. End-of-year sales at dealers or private sellers upgrading to a new model can also mean better deals.
