### **Pros and Cons of Buying a 1988 1994 BMW E32 (735i/740i) with the 1138273 Power Steering Gear Rack and Pinion**

#### **Pros**

1. **Classic BMW Driving Experience**

The E32 series, particularly the 735i and 740i, offers a refined yet engaging driving experience. The M50/M52 engines (depending on model year) provide strong performance with smooth power delivery, making it enjoyable on both city streets and highways. The manual transmission models (if available) enhance the driver engagement.

2. **Reliability of the M50/M52 Engines**

When properly maintained, the M50 (pre-1994) and M52 (1994 ) engines are robust and capable of lasting well over 200,000 miles with regular servicing. The inline-six architecture is durable, and common issues (like head gasket failures) are rare in well-kept examples.

3. **Luxury and Comfort**

The E32 is a full-size luxury sedan with high-quality interior materials, spacious seating, and a quiet cabin. The suspension is well-tuned for comfort, making it a pleasant car for daily driving or long trips.

4. **Strong Resale Value for Classics**

BMW E32s, especially the 735i and 740i, hold their value well in the classic car market. A well-documented example can appreciate significantly over time, making it a smart long-term investment.

5. **Aftermarket Support and Modifications**

The E32 has a strong aftermarket community, offering a wide range of performance upgrades (e.g., exhaust systems, suspension kits, ECU tuning) and cosmetic enhancements (e.g., wheels, interior upgrades). This allows owners to tailor the car to their preferences.

6. **Timeless Design**

The E32 s styling is iconic, blending BMW s signature design language with a luxurious, executive aesthetic. It remains a desirable car for enthusiasts and collectors alike.

7. **Potential for High Performance**

With the right modifications (e.g., forced induction, upgraded suspension, or a manual transmission swap), the E32 can achieve impressive power outputs while retaining its classic character.

---

#### **Cons**

1. **Maintenance Costs**

While the E32 is reliable, it is not a budget-friendly car to maintain. BMW parts, especially for older models, can be expensive, and labor costs at specialty shops add up. Common areas of concern include:

- **Power steering gear rack and pinion (1138273):** This component is known for wear, often requiring replacement every 80,000 120,000 miles. The 1138273 rack is a common issue, and while it can be rebuilt or replaced, parts and labor are costly.

- **Suspension components:** Bushings, shocks, and control arms wear out over time and may need frequent replacement.

- **Electrical system:** Older BMWs are prone to electrical gremlins, such as faulty sensors, wiring issues, or failing alternators.

2. **Rust and Structural Issues**

Many E32s, especially those from the late '80s and early '90s, suffer from rust, particularly in the wheel wells, rocker panels, and subframe. A thorough inspection is essential to avoid buying a car with hidden structural damage that could compromise safety.

3. **Transmission Wear**

The Getrag ZF 5HP19 (automatic) and GM 4T60-E (manual) transmissions are robust but can develop leaks or rough shifting over time. The automatic transmission, in particular, may require fluid changes and potential rebuilds if neglected.

4. **Fuel Economy Limitations**

The 735i and 740i are not fuel-efficient by modern standards, averaging around 16 18 MPG (city/highway). This can add up in cost over time, especially for daily driving.

5. **Parts Availability and Lead Times**

While BMW parts are widely available, some specialty components (e.g., rare interior trims, specific suspension parts) may have long lead times or require ordering from overseas. This can delay repairs or modifications.

6. **Potential for Hidden Problems**

- **Timing chain stretch or tensioner failure** (M50/M52 engines).

- **Water pump failure** (often linked to timing chain issues).

- **Exhaust manifold cracks** (especially on M50 engines).

- **A/C system leaks** (common in older models).

7. **Insurance Costs**

Classic BMWs can be expensive to insure, particularly if the car is valued highly. Full-coverage insurance may be necessary to protect against accidents or theft, adding to the overall cost of ownership.

### **Ending Conclusion**

The 1988 1994 BMW E32 (735i/740i) with the 1138273 power steering rack and pinion is a fantastic choice for enthusiasts who appreciate classic luxury, driving dynamics, and long-term potential. However, it is not a car for casual drivers or those on a tight budget. The power steering rack is a known weak point, but if the car has been well-maintained and inspected thoroughly, it can be a rewarding purchase.

The E32 s strengths lie in its performance, comfort, and timeless appeal, but its weaknesses high maintenance costs, rust susceptibility, and potential for hidden mechanical issues must be carefully considered. A buyer should be prepared for regular upkeep, budget for potential repairs (especially the power steering rack), and ensure the car has a clean service history.

### **Recommendation**

1. **Get a Pre-Purchase Inspection (PPI):** Hire a BMW specialist or a trusted mechanic to thoroughly inspect the car, focusing on the power steering rack, suspension, engine condition, and rust.

2. **Verify Service History:** A well-documented car with regular oil changes, timing belt replacements (if applicable), and power steering rack maintenance is far more reliable.

3. **Budget for Repairs:** Set aside funds for potential issues, especially if the power steering rack has been neglected. Replacing the rack can cost $800 $1,500 or more, depending on labor and parts.

4. **Consider a Manual Transmission:** If available, a manual E32 offers better driving engagement and may be slightly more reliable than the automatic.

5. **Buy from a Reputable Seller:** Deal with a BMW specialist, a trusted private seller with full disclosure, or an auction with a return policy (e.g., Bring a Trailer, RM Sotheby s).

6. **Test Drive Thoroughly:** Pay attention to steering feel, suspension condition, and any unusual noises or leaks.

For the right buyer someone who values classic BMWs, enjoys driving, and is willing to invest in maintenance the E32 is an excellent choice. For others, the costs and potential hassles may outweigh the enjoyment. Always prioritize a car that has been cared for over one that promises "great potential."
