### **Pros and Cons of Buying a 2005 2012 Porsche 997 Boxster (987.1) with a Right Windshield Cowl Cap Cover**

#### **Pros**

1. **Classic Porsche Design and Driving Experience**

The 997 Boxster is widely regarded as one of Porsche s most refined and enjoyable sports cars. Its lightweight construction, rear-wheel-drive dynamics, and precise handling make it a driver s car. The 997 generation introduced improvements over the 996, including better aerodynamics, a more comfortable interior, and a more engaging road presence.

2. **Strong Engine Options**

The 997 Boxster comes with a variety of engines, including the naturally aspirated **3.4L Flat-6 (325 hp)** and the turbocharged **3.6L Flat-6 (350 hp in the S version)**. The NA engine is reliable and fun to drive, while the S version offers more power and a sportier feel. The 997.1 (2005 2009) and 997.2 (2010 2012) models share many mechanical components, ensuring parts availability.

3. **Reliability and Longevity**

With proper maintenance, the 997 Boxster is known for lasting well beyond 100,000 miles. The 997.1 models (pre-2010) are slightly less refined than the 997.2 but are still robust. The 997.2 introduced minor updates, including a revised suspension and improved interior materials. Both generations are well-supported by Porsche and aftermarket parts.

4. **Strong Aftermarket and Customization Potential**

The 997 Boxster has a dedicated fanbase, leading to a thriving aftermarket for modifications. Owners can easily find performance upgrades (e.g., exhaust systems, suspension kits, or engine tuning), as well as cosmetic enhancements (e.g., body kits, wheels, or interior upgrades). The right windshield cowl cap cover you mentioned is a minor but noticeable detail that can improve aerodynamics and aesthetics.

5. **Resale Value and Collectibility**

The 997 Boxster holds its value well, especially lower-mileage examples. The 997.2 models (2010 2012) are slightly more desirable due to their refinements, but both generations are sought after by enthusiasts. Some variants, like the **Boxster S or Carrera S**, appreciate faster than standard models.

6. **Convertible Practicality**

While not as spacious as a coupe, the Boxster s convertible roof is quick to deploy and offers a more open, airy driving experience. The 997 s roof mechanism is reliable, though occasional maintenance (e.g., seals, cables) may be needed over time.

7. **Sporty Yet Comfortable**

The 997 Boxster strikes a balance between sportiness and comfort. The suspension can be adjusted for a firmer or softer feel, and the interior is well-padded with quality materials (though some wear can occur over time). The manual transmission models are particularly engaging for driving enthusiasts.

#### **Cons**

1. **Maintenance Costs**

- **Engine oil changes** (every 6,000 10,000 miles, depending on driving conditions).

- **Timing belt and water pump replacement** (typically every 60,000 100,000 miles; failure can be catastrophic).

- **Suspension components** (shocks, struts, bushings, and control arms wear out over time).

- **Brakes** (high-performance brakes require frequent pad and rotor replacements).

- **Transmission fluid changes** (especially for automatic models).

- **Exhaust and emissions systems** (catalytic converters and oxygen sensors can fail and are costly to replace).

A well-maintained 997 Boxster can be affordable to own, but neglecting maintenance will lead to expensive repairs.

2. **Common Wear Items**

- **Rear differential seals** (leaking fluid is a frequent issue; replacement is labor-intensive).

- **Front strut mounts and control arm bushings** (wear can lead to clunking noises and poor handling).

- **Convertible roof seals and cables** (can leak water and require periodic lubrication).

- **Exhaust manifold gaskets** (common failure point, especially on NA engines).

- **Clutch (if manual)** (Porsche clutches are durable but can wear out with aggressive driving).

3. **Aging Interior and Comfort**

While the 997 Boxster interior is well-built, it shows its age compared to modern vehicles. The seats, though supportive, can become uncomfortable over time, especially for taller drivers. The infotainment system (if equipped) is basic by today s standards, and the lack of modern driver aids (e.g., adaptive cruise control, lane-keeping assist) can be a drawback for some.

4. **Fuel Economy**

The 997 Boxster is not known for its efficiency. The NA 3.4L engine averages around **18 20 MPG combined**, while the S version is slightly worse. This can add up in fuel costs, especially for daily driving.

5. **Rust and Corrosion**

Porsche has a reputation for rust issues, particularly in the wheel wells, subframe, and rear quarter panels. A thorough inspection of the undercarriage is essential before purchasing. Salt exposure (if driven in snowy regions) accelerates rust, so check for signs of corrosion in the wheel arches, rocker panels, and suspension components.

6. **Limited Cargo Space**

The Boxster s convertible roof and rear seats (if equipped) reduce cargo capacity compared to a coupe. The trunk is small, and the rear seats are not very spacious, making it less practical for families or long trips with luggage.

7. **Depreciation and Insurance Costs**

While the 997 Boxster holds value better than many sports cars, it still depreciates over time. Insurance costs can be higher than for a sedan or SUV, especially for newer models or high-performance variants. Theft is also a risk, as Porsches are often targeted.

8. **Minor Issues with the Right Windshield Cowl Cap Cover**

- **Installation can be tricky** if not done properly, potentially leading to gaps or improper sealing.

- **Aftermarket covers may not fit perfectly** on all models, especially if the car has been modified or has unique bodywork.

- **Removal for maintenance** (e.g., accessing the radiator or hood latch) can be inconvenient if not installed correctly.

---

#### **Conclusion**

The **2005 2012 Porsche 997 Boxster (987.1)** is a fantastic choice for enthusiasts who prioritize driving dynamics, classic Porsche charm, and a balance of sportiness and comfort. It offers a rewarding ownership experience with proper maintenance, strong reliability, and a thriving aftermarket. The right windshield cowl cap cover is a minor but worthwhile upgrade for aerodynamics and aesthetics.

However, potential buyers should be prepared for **higher maintenance costs**, **common wear items**, and **aging comfort features**. Rust, fuel economy, and limited practicality are also factors to consider. If you re looking for a **daily driver**, the Boxster is manageable but not as convenient as a modern sedan. If you re a **weekend driver or collector**, it s an excellent investment.

### **Recommendation**

- You love Porsche s driving dynamics and classic design.

- You re prepared for regular maintenance and can budget for potential repairs.

- You prioritize fun over practicality and are okay with a smaller interior.

- You plan to keep the car for the long term (10 years) and enjoy working on it.

- You find a **well-documented, low-mileage example** (under 60,000 miles) with a clean service history.

- You need a practical, low-maintenance vehicle for daily use.

- You re not comfortable with higher repair costs or mechanical work.

- You live in a harsh climate (salt, extreme heat/cold) and the car shows signs of rust.

- You expect modern features like advanced infotainment or driver aids.

**Final Verdict:** The 997 Boxster is a **fantastic sports car** for the right owner one who appreciates its heritage, driving experience, and the challenge of maintaining a premium vehicle. If you re passionate about Porsches and can commit to its care, it s an excellent purchase. If you re looking for a hassle-free or ultra-practical car, consider alternatives like a modern BMW Z4 or a well-maintained used Audi TT.
