### **Pros and Cons of Buying a 1938 1960 Studebaker Commander (1540787, 6-cylinder or V8, Thermostat 170 NOS)**

#### **Pros**

1. **Classic American Design and Prestige**

The Studebaker Commander from this era is a well-regarded classic car, known for its distinctive styling, including the iconic "bullet-nose" front end (on later models) and clean, aerodynamic lines. Owning one places you in a community of enthusiasts who appreciate vintage American automotive craftsmanship.

2. **Strong Engine Options**

- The **6-cylinder** (available in early models) is a reliable, underrated engine with a smooth, torquey character. It s simpler to maintain than a V8 and often more fuel-efficient for its time.

- The **V8** (introduced in 1939) is more powerful, offering better acceleration and a more modern driving experience for the era. The 1950s V8 models, in particular, are highly sought after for their performance and rarity.

3. **Solid Mechanical Construction**

Studebakers of this era were built with durability in mind. The **1950s models** (especially the 1953 1956 Commanders) feature improved suspension, better brakes, and more refined engineering compared to earlier years. The **1950 1956 models** often have a reputation for reliability, especially when well-maintained.

4. **Availability of Parts and Restoration Support**

- Studebaker parts are still available from specialty suppliers, though some rare components (e.g., NOS thermostats, specific carburetors, or wiring harnesses) may require sourcing from collectors or eBay.

- The **1950s models** benefit from a larger restoration community, with aftermarket support for engines, transmissions, and bodywork.

- The **1938 1942 models** are rarer, making them more challenging to restore but also more valuable to collectors.

5. **Potential for Customization and Modifications**

- The Commander chassis is sturdy and adaptable, allowing for modifications like **engine swaps** (e.g., modern V8s or high-performance small-blocks), **suspension upgrades**, or **restomods** (restored with modern comforts).

- The **V8 models** can be tuned for better performance, though originality is often prioritized in classic car circles.

6. **Investment Potential**

- Well-preserved or restored **1950s Commanders** (especially V8 models) appreciate in value, particularly if they are rare or have historical significance.

- The **1938 1942 models** are more collectible due to their scarcity, making them a better long-term investment for serious collectors.

7. **Driving Experience**

- The **6-cylinder** offers a relaxed, old-school cruising feel with good low-end torque.

- The **V8** provides a more engaging, responsive drive, especially in later models with improved power delivery.

- The **1950s models** have a more modern feel compared to earlier Studebakers, with better handling and comfort.

8. **Community and Events**

- Studebaker enthusiasts are passionate and active, with clubs (e.g., **Studebaker Drivers Club**) hosting meets, rallies, and restoration workshops.

- Showing a Commander at classic car events can be rewarding, especially for V8 models or rare variants.

#### **Cons**

1. **High Maintenance and Restoration Costs**

- **Rust** is a major concern, especially on **pre-1950 models** and those from wet climates. Frame rust can be catastrophic and expensive to repair.

- **Originality vs. Restoration**: Restoring a Studebaker to factory condition can be time-consuming and costly, particularly for **1938 1942 models** with limited parts availability.

- **Electrical Systems**: Older models (pre-1950) often have fragile wiring, requiring careful restoration to avoid shorts or failures.

2. **Engine and Drivetrain Reliability Issues**

- **6-Cylinder Engines**: While robust, they can suffer from **valve seat wear, head gasket leaks, or timing chain issues** over time. Later models (post-1948) are more reliable.

- **V8 Engines**: The **1950 1956 V8s** are generally stronger but can develop **oil leaks (valve cover, oil pan), rod bearing wear, or carburetor problems**. The **1953 1956 models** with the **259ci V8** are the most reliable.

- **Transmissions**: Original **3-speed manuals** and **2-speed automatics** (pre-1956) can be finicky. Later **4-speed manuals** and **Hydra-Matic** (1956) are more modern but may still require attention.

- **Differential and Axles**: Original **hypoid axles** can wear out, and **differential seals** often leak. Upgrading to modern axles is common in restored cars.

3. **Fuel and Emissions Compliance**

- **Smog checks** (in states like California).

- **Modifications** (e.g., **EPA-approved carburetors, exhaust systems**) to pass emissions.

- **Special permits** for classic cars (varies by state).

- **Fuel Quality**: Older engines are sensitive to modern fuel additives and ethanol blends, which can damage gaskets and carburetors.

4. **Driving Practicality**

- **Size and Maneuverability**: The Commander is a **large, heavy car** (especially post-1950 models), making parking and city driving challenging.

- **Brakes**: Original **drum brakes** (pre-1956) are weak compared to modern standards. Upgrades (e.g., **disc brakes, power assist**) are often necessary for safe driving.

- **Comfort**: Older models lack modern suspension tuning, leading to a **harsher ride** on rough roads. Later models (1950s) are more comfortable but still not as smooth as modern cars.

5. **Parts Scarcity and Cost**

- **Original Parts**: Many components (e.g., **NOS thermostats, carburetors, wiring harnesses**) are expensive or hard to find. The **1938 1942 models** are particularly challenging.

- **Replacement Parts**: Aftermarket parts exist but may not fit perfectly, requiring fabrication or modification.

- **Labor Costs**: Restoring a Studebaker often requires **specialized mechanics**, increasing repair expenses.

6. **Depreciation Risk**

- Unlike some classic cars (e.g., Ford Mustangs, Chevys), **Studebakers do not hold value as well** unless they are **rare, well-documented, or in pristine condition**.

- **Project Cars**: An unfinished or poorly restored Commander may lose value quickly, especially if it s not a desirable model (e.g., early 6-cylinder vs. late V8).

7. **Insurance Challenges**

- **Classic car insurance** is available but often **more expensive** than standard coverage, especially for high-value or rare models.

- **Driving Habits**: Many insurers require **limited annual mileage** (e.g., under 1,000 miles/year) to qualify for classic car rates.

8. **Time and Commitment**

- Restoring a Studebaker is a **long-term project** that demands **mechanical skill, patience, and financial investment**.

- **Storage**: A classic car needs **proper storage** (garage, climate-controlled) to prevent rust and damage.

- **Maintenance**: Even a restored car requires **regular upkeep** (oil changes, brake inspections, rust proofing) to stay roadworthy.

### **Conclusion**

Buying a **1938 1960 Studebaker Commander** (especially the **V8 models from 1950 1956**) is a rewarding but challenging endeavor. It appeals to those who appreciate **classic American design, mechanical complexity, and the joy of restoration**. However, it also requires **significant time, money, and patience** to bring it to a driveable or show-ready condition.

- **Well-documented, low-mileage examples** (especially **1953 1956 V8 Commanders**) with **minimal rust or mechanical issues**.

- **Models that have already undergone some restoration** (e.g., **engine rebuilt, rust repaired**) but still retain originality where possible.

- **Cars with clear ownership history** to verify authenticity and avoid "Frankenstudebakers."

- **Heavily rusted or structurally compromised** examples (e.g., **pre-1950 models with frame rot**).

- **Project cars with unclear restoration needs** (e.g., **no engine, missing panels, unknown history**).

- **Models requiring extensive emissions modifications** if you plan to drive them legally
