The Porsche Boxster, a mid-engine roadster, has captivated enthusiasts since its debut in the late 1990s. Choosing the right Boxster can be daunting, given the various generations and model year updates. This guide aims to provide clarity, helping you navigate the Boxster landscape and identify the best years to buy, while also highlighting some models to potentially avoid.
Porsche Boxster: Model Year Overview
| Model Year | Key Features/Improvements | Potential Issues/Concerns |
|---|
Detailed Explanations
Model Year: This column represents the specific year the car was manufactured and sold. It's important to note that a car manufactured in late 2004, for instance, might be sold as a 2005 model.
Key Features/Improvements: This column outlines the notable changes, upgrades, or new features introduced in a particular model year compared to its predecessors. This could include engine improvements, cosmetic changes, technological advancements, or handling enhancements. Understanding these features helps you assess the value and desirability of each model year.
Potential Issues/Concerns: This column highlights common problems or potential reliability issues associated with specific model years. This information is crucial for making an informed decision and budgeting for potential repairs. These issues can range from engine-related concerns (like IMS bearing failure in early models) to electrical glitches or specific component failures.
986 Generation (1997-2004)
The original Boxster, the 986, offered a taste of Porsche performance at a (relatively) accessible price point. However, it wasn't without its flaws.
-
1997-1999: These early models are the most affordable but also the most prone to the infamous IMS (Intermediate Shaft) bearing failure. This failure can lead to catastrophic engine damage. Additionally, rear main seal (RMS) leaks and cracked cylinder heads are more prevalent in these years. The plastic rear window on the convertible top is also prone to cracking and clouding. The dual-row IMS bearing used in these years is considered less reliable than the single-row bearing introduced later.
-
2000-2002: Porsche made improvements to the engine and addressed some early reliability concerns. However, the IMS bearing issue remained a potential problem, although statistically less frequent than in the earlier years. The introduction of the single-row IMS bearing occurred during this period, but it's still a point of concern. The introduction of a glass rear window was a welcomed improvement.
-
2003-2004: The final years of the 986 saw further refinements, including a redesigned interior and exterior. The 3.2-liter Boxster S offered a significant performance boost. While the IMS bearing issue still existed, its frequency was further reduced, making these models a slightly safer bet. The revised headlights and taillights gave the car a more modern appearance.
Recommendation: If considering a 986, prioritize models from 2003-2004, and factor in the cost of an IMS bearing replacement as preventative maintenance, regardless of the car's history. Budget for potential RMS leaks as well.
987 Generation (2005-2012)
The 987 generation represented a significant step forward in terms of design, performance, and refinement.
-
2005-2008 (987.1): These models featured a more aggressive and modern design. The base engine was a 2.7-liter, while the Boxster S boasted a 3.2-liter (later a 3.4-liter). While the IMS bearing issue persisted in the early 987.1 models, it's considered less common than in the 986 generation. However, bore scoring (especially in the 3.4-liter engine) became a new concern. This involves wear on the cylinder walls, leading to reduced performance and potential engine failure. Look for signs of excessive oil consumption or unusual engine noises.
-
2009-2012 (987.2): The 987.2 models received a major overhaul, including direct fuel injection (DFI) engines. These engines were more powerful and fuel-efficient. The IMS bearing issue was eliminated in these models. However, DFI engines can be susceptible to carbon buildup on the intake valves, requiring periodic cleaning. The introduction of the PDK (Porsche Doppelkupplung) dual-clutch transmission was a significant improvement over the traditional Tiptronic automatic. The 987.2 models also featured updated styling and improved interior materials.
Recommendation: The 987.2 generation (2009-2012) is generally considered the sweet spot for the Boxster. The elimination of the IMS bearing issue and the introduction of DFI engines make them more reliable and enjoyable to drive. If considering a 987.1, thoroughly inspect for bore scoring.
981 Generation (2013-2016)
The 981 generation marked another significant leap forward in design and performance.
- 2013-2016: The 981 boasted a lighter chassis, more powerful engines, and a more sophisticated interior. The base engine was a 2.7-liter, while the Boxster S featured a 3.4-liter. The 981 is generally considered very reliable. However, some owners have reported issues with the high-pressure fuel pump in the DFI engines. The styling is widely regarded as one of the best in the Boxster's history. The handling is incredibly sharp and responsive, making it a joy to drive on twisty roads.
Recommendation: The 981 is an excellent choice for a modern and reliable Boxster. While not completely immune to issues, its overall reliability is significantly better than the earlier generations.
718 Generation (2017-Present)
The 718 generation introduced turbocharged four-cylinder engines to the Boxster lineup, a controversial move for some purists.
- 2017-Present: The base 718 Boxster features a 2.0-liter turbocharged four-cylinder, while the Boxster S has a 2.5-liter version. The 718 is generally reliable, but the four-cylinder engine sound is a point of contention for many. Some owners have reported issues with the water pump and turbocharger wastegate actuator. Later models have seen the return of the flat-six engine in the GTS 4.0 and Spyder variants, addressing the sound concerns.
Recommendation: The 718 offers modern performance and technology. If the four-cylinder engine sound doesn't bother you, it's a good choice. Otherwise, consider the GTS 4.0 or Spyder for the classic flat-six experience.
Models to Potentially Avoid (or Approach with Caution)
-
Early 986 models (1997-1999): Due to the higher incidence of IMS bearing failure and other early production issues. A thorough pre-purchase inspection is crucial, and budgeting for an IMS bearing replacement is highly recommended.
-
987.1 Boxster S (2005-2008): Due to the potential for bore scoring, especially in the 3.4-liter engine. A compression test and leak-down test are essential to assess engine health.
Frequently Asked Questions
-
What is the IMS bearing issue? The IMS bearing is a critical component in the engine that can fail, leading to catastrophic engine damage. It's more prevalent in earlier Boxster models.
-
How much does it cost to replace the IMS bearing? The cost can range from $2,000 to $4,000, depending on the shop and the parts used.
-
What is bore scoring? Bore scoring is wear on the cylinder walls, leading to reduced performance and potential engine failure. It's a concern in some 987.1 Boxster S models.
-
