### Pros and Cons of Buying a 1986-1988 Ford Thunderbird (E8SZ13A613A) with a High-Mount Third Brake Light
#### **Pros:**1. **Classic Design and Prestige** The Thunderbird from this era is iconic, blending luxury, performance, and a distinctive American muscle-car aesthetic. It carries a sense of nostalgia and prestige that many collectors and enthusiasts appreciate.
2. **V8 Engine Options** The 1986 1988 Thunderbirds were available with powerful V8 engines, including the **5.0L (302 cubic inch) Windsor** (225 240 hp) and the **5.8L (351 cubic inch) Cologne** (200 220 hp). These engines offer strong performance, especially when modified, and are beloved by tuning communities.
3. **Comfortable and Spacious Interior** The Thunderbird was designed as a personal luxury car, featuring a roomy cabin with high-quality materials (especially in higher trims like the **LSC or Grand LSC**). The front seats are particularly comfortable for long drives, and the rear seats provide decent space for passengers.
4. **Reliability of the Base Models** While later models had some reliability issues, the **1986 1988 Thunderbirds** (especially the early 1986 models) are generally considered more robust than their successors. The **5.0L Windsor V8** is a well-proven engine if maintained properly.
5. **Modifiable and Tunable** The Ford E-series Thunderbirds (especially the 5.0L models) are highly tunable. Aftermarket support is strong, with options for forced induction (turbocharging, supercharging), engine swaps (e.g., the **5.8L Cologne, 6.4L Triton, or even LS engines**), and suspension upgrades.
6. **Collectible Status** Certain models, particularly the **1986 1987 Thunderbirds**, are sought after by collectors. The **LSC (Limited Sport Coupe)** and **Grand LSC** trims are especially valuable, making them good long-term investments if well-preserved.
7. **Manual Transmission Option** Unlike later models, some 1986 1988 Thunderbirds were available with a **4-speed manual transmission**, which is a major selling point for driving enthusiasts who prefer direct engagement with the engine.
8. **Good Handling for a Full-Size Car** While not a sports car, the Thunderbird handles better than many of its contemporaries due to its **live rear axle and solid rear end**, which can be upgraded with aftermarket parts for improved stability.
9. **Parts Availability** As a classic Ford, parts are widely available, though some aftermarket support may be needed for less common components. The **E-series Thunderbird** is not as obscure as some muscle cars, so finding replacements is generally easier than for rare models.
10. **Potential for Restoration Value** If the car is in decent condition, a well-done restoration could significantly increase its value, especially for rare trims or special editions.

#### **Cons:**1. **High-Mount Third Brake Light (HML) Issues** The **1986 1988 Thunderbirds** were among the first to feature a **high-mount third brake light**, which was prone to **electrical failures, wiring issues, and mechanical failures** (e.g., the light assembly breaking or the wiring harness degrading). This can be a **major annoyance and potential safety hazard** if not addressed.
2. **Rust and Corrosion** Many Thunderbirds from this era suffer from **frame rust**, especially in the **wheel wells, rocker panels, and rear quarter panels**. A thorough inspection is essential to avoid buying a car with structural compromise.
3. **Electrical Problems** The **1980s Ford electrical systems** were not as reliable as modern ones. Issues like **failing alternators, voltage regulators, and wiring harness failures** are common. The **high-mount light system** itself is often a weak point.
4. **Transmission and Drivetrain Wear** The **4-speed automatic (C4) and 5-speed automatic (5R50)** transmissions in these models can be finicky, especially if not maintained properly. **Slipping gears, delayed engagement, and solenoid failures** are frequent complaints.
5. **Fuel Injection and Engine Reliability** While the **5.0L Windsor** is robust, **fuel injectors, sensors, and PCM (Powertrain Control Module) issues** can arise over time. The **EEC-IV system** (used in 1986 1988) is more complex than earlier carbureted systems and requires proper tuning.
6. **Suspension and Steering Wear** The **solid rear axle** and **front strut suspension** can develop **worn bushings, ball joints, and shocks**, leading to poor handling. The **steering rack** (if equipped) may also need attention.
7. **Interior Wear and Tear** The **upholstery, carpets, and dashboard materials** from this era are prone to cracking, fading, and general deterioration. A full interior refresh may be needed for a show-quality car.
8. **Emissions and Modern Compliance** If you plan to drive this car frequently, **modern emissions regulations** may require modifications (e.g., **OBD-II compliance, updated catalytic converters**). Some states have **smog check requirements** that could be problematic.
9. **Cost of Maintenance** While parts are available, **labor costs for classic cars can be high**, especially if you need specialized mechanics. **Timing belt replacement (if applicable), valve cover gaskets, and fuel system upgrades** add up quickly.
10. **Potential for Hidden Problems** Like many classic cars, **1986 1988 Thunderbirds may have hidden issues** such as:- **Leaking differentials or rear end seals**
- **Worn-out water pumps or thermostats**
- **Corroded brake lines or master cylinders**
- **Exhaust manifold leaks (common in the 5.0L Windsor)**
