### **Pros and Cons of Buying a Used 2015 2023 Dodge Challenger (6.4L Hemi or 6.2L V8) with a Fuel Tank Replacement (Part # 9660948557)**

#### **Pros**

1. **Powerful Engine Options**

- The **6.4L Hemi V8** (2015 2023) produces **470 490 hp** and **470 lb-ft of torque**, making it one of the most capable muscle cars in its class. It handles well, accelerates quickly, and has strong towing capacity (up to **5,000 lbs** with proper setup).

- The **6.2L V8** (2015 2016) is slightly less powerful (**470 hp**) but still offers strong performance and is often more fuel-efficient than the 6.4L. It s also a good option if you prefer a slightly more refined drive.

2. **Strong Resale Value & Brand Loyalty**

- The Challenger has maintained a loyal fanbase, keeping demand high and resale values relatively stable compared to some competitors. This means you may find a good used example without excessive depreciation.

3. **Durability & Reliability (When Maintained Properly)**

- The **6.4L Hemi** is known for its longevity if regularly serviced. Many examples with **100,000 miles** run well with proper maintenance (oil changes, cooling system care, etc.).

- The **6.2L V8** is also robust, though it may have slightly more minor wear issues (e.g., valve cover gaskets, oil leaks) compared to the 6.4L.

4. **Fuel Tank Replacement (Part # 9660948557) Indicates Care**

- A **new fuel tank** suggests the previous owner took basic maintenance seriously. Fuel tanks can develop leaks or corrosion over time, so a replacement is a positive sign that the car hasn t been neglected.

- The Challenger s **fuel system** (including injectors and fuel rails) is generally reliable, but a fresh tank reduces the risk of future leaks or contamination.

5. **Driving Experience & Comfort**

- The Challenger offers a **smooth ride** with well-tuned suspension (especially in the **SRT8** or **R/T** trims).

- The **interior is spacious**, with modern features (even in older models) like **USB ports, Bluetooth, and a decent infotainment system** (though the screen can be outdated).

- The **6-speed automatic transmission** (in most models) is smooth and reliable, though some early 2015 2016 examples may have minor shifter issues.

6. **Customization & Aftermarket Support**

- The Challenger has a **thriving aftermarket**, with performance parts (exhaust, suspension, ECU tuning) readily available.

- Body kits, lift kits, and engine swaps (e.g., **LS V8, Hemi, or even turbocharged setups**) are popular modifications.

- The **SRT8** (6.4L supercharged) is a favorite for enthusiasts looking for **600 hp** with minimal effort.

7. **Towing & Hauling Capability**

- With the **proper transmission (6-speed auto or 8-speed in later models) and cooling upgrades**, the Challenger can tow **up to 5,000 lbs** (with a trailer brake controller and proper hitch).

- The **6.4L Hemi** is well-suited for **light-duty towing** (e.g., small trailers, boats) if cooled adequately.

8. **Aesthetic Appeal & Muscle Car Prestige**

- The Challenger s **bold styling** (especially the **2018 facelift**) makes it stand out on the road.

- Owning a **modern muscle car** provides a sense of nostalgia while still feeling current.

---

#### **Cons**

1. **High Maintenance Costs**

- **Oil changes must be done frequently** (every **5,000 miles** for the 6.4L Hemi to prevent sludge buildup).

- **Cooling system failures** (water pump, thermostat, hoses) are common if maintenance is neglected. The **6.4L Hemi** is particularly sensitive to overheating.

- **Transmission fluid changes** (every **30,000 60,000 miles**) are often overlooked, leading to rough shifting or failure.

- **Suspension wear** (struts, bushings, control arms) can be expensive to replace, especially on **high-mileage examples**.

2. **Fuel Economy is Poor**

- The **6.4L Hemi** averages **12 14 MPG highway**, while the **6.2L V8** does slightly better (**14 16 MPG**).

- If you do **heavy towing or frequent highway driving**, fuel costs will add up quickly.

3. **Rust & Corrosion Risks**

- The Challenger is **notoriously prone to rust**, especially in **rockers, wheel wells, and undercarriage**.

- Even with a **new fuel tank**, check for **frame rust, body panel corrosion, and wheel well leaks** before purchasing.

- **Snow-belt and coastal regions** have higher rust risks.

4. **Transmission Issues (Early Models)**

- Some **2015 2016 6-speed automatics** have reported **rough shifting, delayed engagement, or solenoid failures**.

- **8-speed automatics (2018 )** are more refined but still require **proper fluid changes**.

5. **Supercharger (SRT8) Reliability Concerns**

- The **6.4L supercharged SRT8** is **powerful but complex**. Common issues include:

- **Supercharger pulley bearing wear** (can cause whining noises).

- **Oil leaks from the supercharger housing**.

- **Intercooler failures** (leading to overheating).

- If buying an **SRT8**, ensure it has **proper cooling upgrades** (larger radiator, oil cooler) and **regular maintenance**.

6. **Electrical & Infotainment Glitches**

- Some models have **Uconnect system freezes, Bluetooth connectivity issues, or sensor failures**.

- **Window regulators and door locks** can fail over time, requiring **expensive replacements**.

7. **Resale Depreciation**

- While the Challenger holds value better than some competitors, it still **loses 20% of its value in the first three years**.

- If you plan to sell later, **maintenance records will be crucial** to justify the price.

8. **Limited Off-Road or Heavy-Duty Capability**

- The Challenger is **not an off-road vehicle** it lacks **locking differentials, high ground clearance, or robust suspension tuning**.

- For **serious towing**, consider adding a **performance radiator, transmission cooler, and proper hitch setup**.

9. **Noise & Vibration (Especially in Cabin)**

- The **6.4L Hemi** can be **loud at highway speeds** (exhaust, supercharger whine in SRT8).

- Some models have **wind noise** through the **B-pillars and rear window**.

- **Road noise** can be intrusive in less expensive trims.

10. **Potential Hidden Issues**

- **Timing chain stretch** (less common but possible in the 6.4L).

- **Water pump failures** (often accompanied by **coolant leaks**).

- **Exhaust manifold cracks** (especially on the **6.2L V8**).

- **Suspension bushings wearing out**, leading to **clunking noises**.

---

### **Key Considerations Before Buying**

1. **Mileage & Maintenance History**

- **Ideal mileage:** **Under 80,000 miles** for a **6.2L V8**, **under 100,000 miles** for a **6.4L Hemi** (with **full service records**).

- **Red flags:** No oil change records, **coolant leaks, rough shifting, or exhaust smoke**.

2. **Fuel Tank Replacement (Part # 9660948557) What It Means**

- A **new fuel tank** is a **positive sign**, but verify:

- **Why was it replaced?** (Leak? Corrosion? Accident?)

- **Was it installed by a dealer or shop?** (Dealer work is more reliable.)

- **Check for fuel line leaks** around the tank and sender unit.

- If the tank was replaced due to **corrosion**, inspect the **rest of the fuel system** (lines, pump, injectors).

3. **Engine Choice: 6.2L vs. 6.4L Hemi**

- **6.2L V8:** More fuel-efficient, slightly less power, but **simpler and cheaper to maintain**.

- **6.4L Hemi:** More power, better for towing, but
