### **Pros and Cons of Buying a 1989 1994 BMW 735i (E32) with Sunroof/Moonroof**

#### **Pros**

**1. Classic Luxury and Prestige**

The BMW E32 735i is an iconic luxury sedan from the late 1980s and early 1990s, embodying BMW s engineering excellence and timeless design. Owning one positions you in a niche market of enthusiasts who appreciate vintage German engineering.

**2. Strong Engine and Performance**

The 3.5-liter inline-6 M88 engine produces **240 250 horsepower**, paired with a smooth **ZF 5-speed automatic** (or manual in some models). This provides a balanced blend of power and refinement, making it enjoyable to drive on both highways and winding roads. The engine is robust and can handle modifications if desired.

**3. Reliability (With Proper Maintenance)**

BMW s M88 engine is known for its durability, especially when maintained correctly. Many E32s with low mileage (under 100,000 miles) run reliably if the owner has kept up with **timely oil changes, transmission service, and suspension work**. However, neglect can lead to costly failures.

**4. Classic Sunroof/Moonroof (If in Good Condition)**

The sunroof/moonroof adds a touch of luxury and opens up the cabin for fresh air. If the mechanism is intact and properly sealed, it enhances the driving experience. However, older sunroofs can leak or fail over time, requiring attention.

**5. Resale Value and Collectibility**

The E32 735i is a sought-after classic, especially in good condition. Well-preserved examples hold value, and some modifications (like engine swaps or interior upgrades) can increase desirability among collectors.

**6. Driving Dynamics and Handling**

The E32 features **recirculating ball steering, independent rear suspension, and a solid chassis**, making it more nimble than its heavier predecessors. The ride is comfortable yet responsive, with good road-holding characteristics for its size.

**7. Customization Potential**

The E32 platform allows for various upgrades, including:

- **Engine swaps** (e.g., M60 V8, S50 B58, or even modern turbocharged engines)

- **Suspension modifications** (lowering springs, coilovers, or poly bushings for better handling)

- **Interior upgrades** (leather seats, modern infotainment, or restored classic dash)

- **Exterior restyling** (body kits, custom paint, or headlight upgrades)

**8. Community and Support**

There is a strong **BMW E32 owner community**, with forums (e.g., BMW328.net, E32.org), aftermarket parts suppliers, and restoration experts who can assist with repairs and modifications.

---

#### **Cons**

**1. High Maintenance Costs**

BMW s luxury components (e.g., **ZF transmissions, power steering, electrical systems**) are notoriously expensive to repair. Common issues include:

- **Transmission failures** (ZF 5HP19/21 can be fragile; some owners opt for a **ZF 5HP22 or manual conversion**)

- **Water pump and timing belt failures** (critical to replace before they cause engine damage)

- **Power steering leaks** (common on older models)

- **Electrical gremlins** (faulty sensors, wiring issues, or failing electronics)

**2. Rust and Structural Issues**

Many E32s suffer from **rust in critical areas**, such as:

- **Wheel wells** (common failure point)

- **Suspension arms and control arms**

- **Floor pans and rocker panels**

A thorough inspection is **mandatory** rust can compromise safety and structural integrity.

**3. Aging Electrical System**

The E32 s electrical system is **outdated by modern standards**, with:

- **Failing fuses and relays**

- **Inconsistent power windows/locks**

- **Faulty sensors** (e.g., speed sensor, oxygen sensor)

- **No modern infotainment** (early models have no CD player or backup camera)

**4. Sunroof/Moonroof Problems**

While a sunroof adds luxury, older models often have:

- **Leaking seals** (leading to water damage in the headliner and dashboard)

- **Stuck or failing mechanisms** (requiring lubrication or replacement)

- **Condensation issues** (can fog up the windshield)

**5. Fuel Economy and Modern Standards**

The 3.5L inline-6 gets **around 16 18 MPG highway**, which is poor by today s standards. Gasoline prices and environmental concerns may make long-distance driving less economical than a modern hybrid or electric vehicle.

**6. Limited Modern Safety Features**

The E32 lacks:

- **Anti-lock brakes (ABS)** (early models may not have it; later ones do)

- **Airbags** (side airbags were optional in some years)

- **Electronic stability control (ESC)**

- **Modern crash safety ratings**

**7. Parts Availability and Lead Times**

While parts exist, **some components (especially rare or discontinued ones) can take weeks or months to arrive**. This can be frustrating during repairs.

**8. High Insurance Costs**

Due to its value and repair costs, **insuring an E32 can be expensive**, especially for younger or inexperienced drivers.

**9. Driving Comfort in Modern Terms**

- **Noisy cabin** (especially with worn suspension and tires)

- **Sluggish acceleration** compared to modern turbocharged engines

- **Limited visibility** (due to large size and lack of modern body styling)

**10. Potential Hidden Problems**

Before buying, investigate:

- **Overheating issues** (water pump, thermostat, radiator)

- **Exhaust leaks** (common in the muffler and catalytic converter)

- **Suspension wear** (worn bushings, shocks, or ball joints)

- **Rust in the subframe and rear axle**

### **Conclusion**

The **1989 1994 BMW 735i (E32) with a sunroof/moonroof** is a **fantastic choice for enthusiasts who appreciate classic luxury, driving dynamics, and the joy of restoring a well-built German sedan**. It offers **strong performance, timeless design, and a strong aftermarket**, making it ideal for those who enjoy **project cars** or **collectible vehicles**.

However, it is **not a plug-and-play daily** for everyone. The **high maintenance costs, potential rust issues, and lack of modern conveniences** make it better suited for:

- **Weekend drivers** who enjoy tinkering and restoring

- **Collectors** who prioritize nostalgia and investment potential

- **Enthusiasts** who want a **driving experience** over pure practicality

If you **budget for repairs, inspect thoroughly for rust and mechanical issues, and are prepared for occasional electrical gremlins**, the E32 can be a **rewarding and enjoyable** purchase. But if you **prioritize reliability, fuel efficiency, and modern safety**, a **modern luxury sedan or a well-maintained E38/E39** might be a better fit.

---

### **Recommendation**

**Buy the E32 735i if:**

You have **mechanical or restoration skills** (or access to a trusted mechanic).

You **enjoy the driving experience** and don t mind occasional repairs.

You **plan to keep it for the long term** (10 years) and treat it like a project.

You **find a well-documented example** with **low mileage (

You **budget for a full inspection** (or do it yourself) before purchasing.

You **prefer modern technology** (infotainment, safety features, fuel efficiency).

The **sunroof/moonroof is leaking or in poor condition** (unless you plan to replace it).

You **don t enjoy the process of restoring a classic car**.

**Final Verdict:**
