### **Pros and Cons of Buying a 1962 1977, 1980 1981, or 1985 1987 Oldsmobile Cutlass with a Standard Motor 12557NGFG Trunk Lock SMP**
#### **Pros**
1. **Classic American Muscle Car Appeal** The Cutlass, particularly in its mid- 60s to early 80s iterations, is an iconic American muscle car with strong styling, performance options, and a cult following. Owning one allows you to drive a piece of automotive history.
2. **Wide Range of Engine Options** Depending on the year, the Cutlass was available with a variety of engines, including:- **V8s (1962 1977):** 350 CID, 400 CID, 455 CID, and even high-performance versions like the 455 Rocket V8.
- **Small-block V8s (1980 1981, 1985 1987):** 307 CID, 350 CID, and 400 CID engines, some with fuel injection.
- **In-line Sixes (1962 1964):** Available in early models, offering a more economical option.
This flexibility means you can choose a model that fits your budget and performance goals.
3. **Strong Aftermarket Support** The Cutlass, especially the **Cutlass Supreme, Cutlass Calais, and Cutlass Cruiser**, benefits from a dedicated aftermarket. Parts like carburetors, ignition systems, suspension components, and body panels are widely available. Performance upgrades (e.g., headers, exhaust, camshafts) are also common.
4. **Reliability of the Trunk Lock SMP (12557NGFG)** The **Standard Motor Products (SMP) 12557NGFG trunk lock** is a durable mechanical lock mechanism. While not as secure as modern electronic locks, it is a simple, reliable system that is easy to repair or replace if it fails. Many older cars use similar trunk lock designs, so finding replacements is straightforward.
5. **Affordability Compared to High-Performance Muscle Cars** While some Cutlass models (especially later V8-equipped ones) can be pricey, they are generally more affordable than high-end muscle cars like Mustangs, Camaros, or Challengers. This makes them accessible to enthusiasts on a budget.
6. **Driving Experience** The Cutlass offers a mix of comfort and performance. Early models (1960s) have a more raw, aggressive feel, while later models (1980s) are smoother and more refined. The ride is comfortable, and many models have solid handling for their size.
7. **Customization Potential** The Cutlass is a great candidate for restoration, modification, or even a "project car." You can easily swap in different engines, suspension setups, or bodywork to create a unique vehicle.
8. **Community and Events** There are numerous Oldsmobile and Cutlass clubs, car shows, and cruises where you can connect with other owners. This community provides support, restoration advice, and a sense of belonging.
9. **Fuel Economy (Compared to V8s)** Some models, particularly those with inline-sixes or smaller V8s (e.g., 307 CID), offer better fuel economy than larger muscle cars, making them more practical for daily driving.
10. **Potential for Low Mileage Examples** Depending on the market, you may find well-preserved Cutlasses with low miles, especially if they were kept as collector cars or in storage.

#### **Cons**
1. **Rust and Structural Issues** Many Cutlasses from the **1960s and early 1970s** suffer from rust, particularly in the floor pans, rocker panels, and wheel wells. Even later models (1980s) can have rust issues if they were driven in harsh climates. A thorough inspection is essential before purchasing.
2. **Engine and Transmission Wear** Older Cutlasses (pre-1980) often have high-mileage engines and transmissions. Common issues include:- **Valve train wear** (especially in older V8s).
- **Rod bearing failure** in high-mileage engines.
- **Transmission problems**, particularly in automatic transmissions (e.g., Turbo-Hydramatic 350, TH400).
- **Fuel system issues** (carburetors, vacuum leaks, distributor problems).
Later models (1980s) may have better reliability, but they still require maintenance, especially if they were not well-maintained.
3. **Electrical System Challenges** Older Cutlasses (pre-1980) often have outdated electrical systems that can be finicky. Issues like:- **Faulty alternators or starters**.
- **Worn wiring harnesses**.
- **Relay or fuse box failures**.
- **Modern electronics compatibility** (e.g., GPS, modern audio systems may require wiring modifications).
Later models (1980s) are more reliable electrically but may still have issues with corrosion in connectors.
4. **Suspension and Steering Wear** Many Cutlasses have worn-out suspension components, including:- **Shock absorbers and struts** (often leaking or shot).
- **Ball joints and tie rod ends** (common wear items).
- **Steering rack or recirculating ball steering** (can be noisy or stiff).
Replacing these parts can be costly, especially if the car has high miles.
5. **Body and Paint Condition** The Cutlass is a large car, and maintaining its paint and bodywork can be expensive. Common issues include:- **Panel rust** (especially on older models).
- **Dent and scratch repair** (due to size, repairs can be labor-intensive).
- **Clear coat fading** (common in older cars exposed to sun).
Restoring the body to showroom condition requires significant time and money.
6. **Fuel and Emissions Compliance** If you plan to drive the car regularly, you may need to address:- **Smog check compliance** (especially in California or other states with strict emissions laws).
- **Modern fuel requirements** (older cars may require leaded fuel or special additives).
- **Exhaust system modifications** (some states require catalytic converters, which can be difficult to find for older cars).
7. **High Maintenance Costs** Older Cutlasses (pre-1980) require frequent maintenance, including:- **Regular valve adjustments** (for pushrod engines).
- **Timing belt or chain replacement** (if applicable).
- **Fluid changes** (transmission, differential, power steering, coolant).
- **Brake system upgrades** (many older cars have drum brakes or worn-out rotors).
Later models (1980s) are more modern but still require diligent upkeep.
8. **Seating and Interior Comfort** The Cutlass is a large car, and while comfortable, the interiors can be:- **Worn or cracked** (especially in older models).
- **Less ergonomic** than modern cars (steering wheel position, gear shift placement).
- **Heavier** (older models can feel sluggish in city driving).
9. **Parts Availability and Cost** While parts are available, some rare or discontinued components (e.g., specific carburetors, rare body panels) can be expensive or hard to find. Prices for OEM parts have risen in recent years due to demand from the classic car market.
10. **Insurance Costs** Classic muscle cars can be expensive to insure, especially if you plan to drive them regularly. Some insurers may charge higher premiums for older, high-performance vehicles, or they may require proof of restoration or limited use.
11. **Driving Experience Limitations** While fun, the Cutlass is not as nimble as modern sports cars or even smaller muscle cars. The **1960s models** can feel heavy and slow to accelerate compared to today s standards. Later models (1980s) are more responsive but still lack modern safety features like stability control or advanced airbag systems.
12. **Potential for Hidden Problems** Many Cutlasses have been poorly maintained over the years. Common hidden issues include:- **Blown head gaskets** (common in older V8s).
- **Warped cylinder heads** (due to overheating).
- **Transmission slippage** (especially in automatic transmissions).
- **Rust in critical areas** (e.g., subframe, rear axle housing).
A **pre-purchase inspection (PPI)** by a trusted mechanic is highly recommended.
