### **Pros and Cons of Buying a 2007 2013 Chevrolet Silverado/GMC Sierra (GM 20809999) with a Power Passenger Side Mirror**

#### **Pros**

1. **Proven Reliability (Early 2000s GM Trucks)**

- The 2007 2013 Silverado/Sierra models (especially pre-2011) are known for their durability, particularly with the **5.3L V8 (L56/LT1)** and **6.0L V8 (LQ9)** engines. Many of these trucks were built to last, especially if maintained properly.

- The **4L60-E or 4L70-E transmissions** (in non-automatic models) are robust, though they require proper fluid changes to avoid failure.

2. **Strong Resale Value & Availability of Parts**

- These trucks are still widely available, meaning parts (mirrors, wiring harnesses, motors, etc.) are easy to find and relatively affordable.

- The **power mirror system** (if functional) is a minor convenience, but replacements are straightforward if something fails.

3. **Good Towing & Hauling Capability**

- With the right engine and drivetrain (e.g., **5.3L V8, 4x4, heavy-duty suspension**), these trucks can tow **up to 8,000 10,000 lbs** with proper setup, making them useful for work or recreation.

- The **frame and suspension** are sturdy, though later models (2011 ) had slight refinements in ride quality.

4. **Lower Purchase Price (Compared to New Trucks)**

- Used examples in this range typically sell for **$5,000 $15,000**, depending on mileage and condition, making them an attractive budget option.

- Financing rates for older trucks are often better than for newer models.

5. **Modification Potential**

- The **GM 2000-series trucks** (including this model) are popular for **lift kits, aftermarket suspension, and engine swaps** (e.g., LS-based engines).

- The **mirror system** can be upgraded or replaced with aftermarket options if needed.

6. **Proven Fuel Efficiency (For a Big Truck)**

- The **5.3L V8** gets **12 15 MPG highway**, which is decent for a full-size truck of its era.

- Diesel options (6.6L Duramax) were available but are less common in this range.

#### **Cons**

1. **Aging Electronics & Potential Mirror Issues**

- The **power passenger mirror** may fail due to **corrosion in the motor or wiring harness**, especially if the truck has seen salt or moisture exposure.

- Some owners report **intermittent power window or mirror issues** due to worn-out switches or faulty relays.

- **Check for rust** in the mirror housing and wiring connections before buying.

2. **Transmission & Drivetrain Wear**

- **Automatic transmissions (4L60-E, 4L70-E, 4L80-E)** can fail if fluids weren t changed regularly, leading to **slipping, rough shifting, or complete failure**.

- **Manual transmissions (4L60-E)** are more durable but require **proper syncro maintenance**.

- **Differential and transfer case fluids** should be **fresh or recently changed** old fluid can cause premature wear.

3. **Fuel Injection & Emissions Issues**

- **Port fuel injectors** (common in 5.3L V8s) can clog over time, leading to **rough idling, misfires, or poor fuel economy**.

- **EGR and DPF (Diesel models)** can fail, requiring costly repairs if not maintained.

- **OBD-II codes** should be checked common issues include **P0420 (catalytic converter), P0171/P0174 (fuel trim), or P0300 (misfire)**.

4. **Suspension & Alignment Wear**

- **Shocks, struts, and bushings** wear out over time, leading to **rough rides, poor handling, or uneven tire wear**.

- **Ball joints and control arms** can fail, causing **clunking noises** or handling issues.

- **Tire age** is critical check for **cracks or bulges** (tires older than 6 10 years should be replaced).

5. **Rust & Body Corrosion**

- **Underbody rust** (especially in the **floor pans, rocker panels, and wheel wells**) is common in older trucks, particularly in snowy or salted regions.

- **Mirror mounts** can rust out, leading to **loose or detached mirrors**.

- **Check for rust** in the **firewall, door jambs, and wheel wells** major rust can require expensive repairs.

6. **Safety & Modern Standards**

- **Lack of modern safety features** (no standard stability control, limited airbag coverage in older models).

- **Blind spots** are larger due to the truck s size, and **backup cameras** were not standard until later models.

- **Fuel economy** is poor by today s standards ( 12 15 MPG highway).

7. **Potential Hidden Costs**

- **Timing belt** (if applicable most 5.3L V8s have a **chain**, but some 6.0L V8s do not).

- **Water pump, thermostat, and hoses** may need replacement if the cooling system hasn t been serviced.

- **Battery and alternator** wear out over time, especially in **cold climates**.

---

### **Key Things to Inspect Before Buying**

- **Engine noises** (ticking, knocking, or whining could indicate **valvetrain or rod bearing issues**).

- **Suspension clunks** (indicates worn bushings or ball joints).

- **Power mirror operation** (test all functions if it doesn t work, it may need a **new motor or wiring repair**).

- **Fluid levels** (oil, coolant, transmission, differential, transfer case).

- **No leaks** (oil, coolant, or power steering fluid).

- **Battery health** (should hold a charge, no corrosion on terminals).

- **Rust** (especially under the truck, wheel wells, and around the mirrors).

- **Electrical issues** (test all power windows, locks, and mirrors).

- **Tire condition** (age, tread depth, and sidewalls for cracks).

- **Seat and steering wheel wear** (if the truck has high mileage, check for excessive wear).

- **Transmission fluid changes** (should be done every **30K 60K miles**).

- **Engine oil changes** (synthetic oil recommended, changes every **5K 7.5K miles**).

- **Suspension and drivetrain service** (ball joints, bushings, differential fluid).

- A **mechanic or truck specialist** can catch hidden issues (e.g., **internal transmission damage, exhaust leaks, or frame rust**).
