### **Pros and Cons of Buying a Used Infiniti WR-O9 (875-AA) with Sunroof (2009 2017) and Related Models (FX35, FX37, FX50, QX70)**

#### **Overview of the WR-O9 (875-AA) Series**

The Infiniti WR-O9 (codenamed 875-AA) is a high-performance, rear-wheel-drive luxury coupe based on the Nissan GT-R platform. It was produced from 2009 to 2017 and shares many components with the Infiniti FX, FXV, and QX70 models, particularly in terms of drivetrain, suspension, and some interior features. The sunroof (or "sunroof motor") is a desirable feature, adding comfort and luxury to the driving experience.

---

### **Pros of Buying a Used WR-O9 (875-AA) with Sunroof**

1. **Performance and Driving Dynamics**

- **GT-R-Based Platform:** The WR-O9 shares the same backbone as the Nissan GT-R, meaning it has a stiff chassis, high-revving V6 (3.7L VR38DETT), and a robust drivetrain. This results in sharp handling, precise steering, and engaging driving dynamics.

- **All-Wheel Drive (AWD):** The AWD system (available in most models) provides excellent traction in various conditions, making it more versatile than a pure RWD car.

- **High Horsepower:** The 3.7L V6 produces **332 370 hp** (depending on the year and trim), which is more than adequate for spirited driving and towing light loads (up to **5,000 lbs** in some trims).

- **Manual Transmission Option:** Early models (2009 2011) offered a **6-speed manual**, which is highly sought after by enthusiasts for its engaging driving experience.

2. **Luxury and Comfort**

- **Premium Interior:** The WR-O9 features high-quality materials, leather seats, power-adjustable seats, and advanced infotainment systems (depending on the year).

- **Sunroof:** The sunroof adds to the luxury feel, providing natural light and ventilation, though it may require occasional maintenance (e.g., seals, motor).

- **Quiet Cabin:** The sound insulation is decent for a performance car, though not as refined as some German luxury vehicles.

3. **Reliability (Compared to Competitors)**

- **Proven Engine:** The 3.7L V6 is a well-known, durable powerplant when maintained properly. Common issues (like oil consumption) are manageable with regular care.

- **Transmission:** The **6-speed automatic** (later models) and **6-speed manual** are generally reliable, though some early automatics may develop transmission fluid leaks over time.

- **AWD System:** The AWD unit is robust, but fluid changes are critical to prevent premature wear.

4. **Resale Value and Enthusiast Appeal**

- **Strong Secondary Market:** The WR-O9 holds its value well due to its performance credentials and rarity compared to other Infiniti models.

- **Modding Community:** There is a dedicated community for WR-O9s, meaning parts, upgrades, and tuning support are available.

5. **Shared Parts with FX/QX70**

- **Cost-Effective Repairs:** Many components (suspension, brakes, interior trims) are shared with the **FX35/FX37/FX50** and **QX70**, reducing repair costs if you ever need parts for these models.

- **Easier Maintenance:** Dealerships and mechanics familiar with Infiniti s luxury lineup may be more comfortable working on these vehicles.

---

### **Cons of Buying a Used WR-O9 (875-AA) with Sunroof**

1. **Common Mechanical Issues**

- **Oil Consumption:** The 3.7L V6 is notorious for **oil burning**, especially in high-mileage examples. Some owners report consuming **1 quart per 1,000 miles** or more, requiring frequent top-ups.

- **Transmission Fluid Leaks:** Early automatic transmissions (pre-2013) may develop **fluid leaks** from the torque converter or seals, leading to rough shifting or failure if ignored.

- **AWD Fluid Leaks:** The AWD unit and transfer case may develop leaks over time, requiring **regular fluid changes** (every **30,000 60,000 miles**).

- **Suspension Wear:** The **coilovers** (if equipped) and **shock absorbers** wear out around **50,000 80,000 miles**, affecting ride quality and handling.

2. **Sunroof-Specific Problems**

- **Motor Failure:** The sunroof motor can fail due to **dust, moisture, or electrical issues**, requiring replacement (typically **$500 $1,200**).

- **Seal Leaks:** Over time, the sunroof seals may degrade, leading to **water leaks** into the cabin during rain.

- **Obstruction Sensors:** Some models have **obstruction sensors** that can malfunction, causing the sunroof to close unexpectedly.

3. **High Maintenance Costs**

- **Labor-Intensive Repairs:** Infiniti dealerships often charge **premium labor rates**, and some repairs (e.g., transmission work) can be expensive.

- **Specialized Parts:** While parts are available, some **aftermarket or OEM components** (e.g., AWD seals, sunroof motors) may require sourcing.

4. **Fuel Economy and Running Costs**

- **Poor MPG:** The V6 engine averages **16 18 MPG city / 22 25 MPG highway**, which is higher than a V8 but still modest for a luxury car.

- **High Insurance Costs:** Due to its performance and value, insurance premiums may be **higher than average**.

5. **Rust and Body Issues**

- **Susceptibility to Rust:** Some early WR-O9s (especially in snowy regions) develop **rust in wheel wells, rocker panels, and undercarriage**.

- **Paint and Trim Wear:** The body kit (air intakes, rear diffuser) can be prone to **dents and scratches** due to its aggressive styling.

6. **Limited Practicality**

- **Two-Seater:** The lack of rear seats makes it **impractical for families or frequent passengers**.

- **Towing Limitations:** While capable of towing, it is **not as strong as a full-size SUV** (e.g., QX70), limiting its utility for heavy loads.
