For enthusiasts and mechanics alike, this part represents a straightforward yet vital component in maintaining the E60 s legendary driving dynamics and interior ambiance.
### **Pros and Cons of Buying a BMW E60 535i/528i (08-10) with a Worn Front Driver Seat Bottom Cushion Track**
#### **Pros**
1. **Premium Driving Experience**
The BMW E60 (2008-2010) is renowned for its refined engineering, powerful performance, and luxury interior. The 535i (with the N54 engine) and 528i (with the N52 engine) offer strong acceleration, smooth power delivery, and excellent handling, making it a joy to drive on both highways and twisty roads.
2. **Strong Resale Value**
BMW s E60 series holds its value relatively well compared to many competitors, especially when well-maintained. The 535i, in particular, remains a desirable model due to its twin-turbo V8 power.
3. **Luxury and Comfort**
The cabin is spacious, well-appointed, and features high-quality materials (depending on trim). The 535i comes with a more premium interior, while the 528i still offers a comfortable and upscale environment.
4. **Reliability (With Proper Maintenance)**
The N52 (528i) and N54 (535i) engines are robust when serviced regularly. The E60 platform is generally sturdy, though some owners report issues with electrical components, suspension wear, and transmission (especially in automatic models).
5. **Aftermarket Support**
The E60 has a strong aftermarket presence, meaning parts (including seats, suspension, and performance upgrades) are widely available. Tuning options (like MHD or BMS) can enhance performance and drivability.
6. **Versatility**
The E60 is available in sedan, Touring (wagon), and M5 variants (if considering a performance-oriented option). The wagon model is particularly practical for long trips.
7. **Classic Status**
The E60 is already a few years into its "classic" phase, meaning parts are becoming more expensive, but it s not yet at the point where finding a used one is difficult. Future appreciation potential exists for well-preserved examples.

#### **Cons**
1. **Worn Front Driver Seat Bottom Cushion Track**
The primary concern here is the seat track degradation. A failing seat track can lead to:- **Increased noise and rattling** from the seat moving excessively.
- **Difficulty adjusting the seat** (if the mechanism is seized).
- **Potential safety risk** if the seat shifts unexpectedly while driving.
- **Higher repair costs** replacing seat tracks can be expensive (typically $300 $600 depending on labor and parts).
- **Resale impact** buyers may be deterred by obvious wear, reducing the car s value.
*Mitigation:* If the track is only slightly worn, it may last another few years. If it s already loose or noisy, budget for a replacement before purchasing.
2. **Electrical Gremlins**
The E60 is notorious for electrical issues, including:- Faulty window regulators.
- Malfunctioning door locks or mirrors.
- Infotainment glitches (especially in older models).
- Sensor failures (e.g., rain sensors, parking sensors).
These issues can be frustrating and costly to repair, though many are fixable with aftermarket parts or professional diagnostics.
3. **Transmission Concerns (Automatic Models)**
The Getrag 6HP21 automatic transmission (common in the 528i) has had reliability issues, including:- Rough shifting or delayed engagement.
- Transmission fluid leaks.
- Premature wear if not serviced properly.
The 535i s ZF 6HP21C is generally more robust but still requires regular fluid changes (every 60,000 80,000 miles).
4. **Suspension and Steering Wear**
After 10 12 years, the E60 s suspension (shocks, struts, bushings) and steering components (rack and pinion, tie rods) may need replacement. Worn suspension affects ride quality and handling precision.
5. **Fuel Economy Limitations**
The 535i s twin-turbo V8 is thirsty, averaging **14 16 MPG combined**, while the 528i s inline-6 is slightly better at **18 20 MPG**. Neither is efficient by modern standards, which may be a drawback for daily commuting.
6. **Maintenance Costs**
BMWs are expensive to maintain, especially with OEM parts. Common high-cost repairs include:- Engine cooling system (water pump, thermostat, hoses).
- Brake system (pads, rotors, calipers).
- Exhaust system (catalytic converters, mufflers).
- Electrical diagnostics (if issues persist).
7. **Depreciation**
While the E60 holds value better than many cars, it still depreciates significantly over time. A 2008 2010 model will likely lose **40 50% of its original value** in 10 years unless it s a low-mileage, well-documented example.
8. **Noise and Vibration**
Some E60s develop road noise (especially in the rear) due to worn weatherstripping or suspension components. The N54 engine (535i) can also produce more vibration at higher RPMs compared to the smoother N52 (528i).

### **Conclusion**
Buying a **2008 2010 BMW E60 535i or 528i with a worn front driver seat bottom cushion track** can be a rewarding purchase if you prioritize driving dynamics, luxury, and long-term enjoyment but it comes with trade-offs. The seat track issue is the most immediate concern, as it can be a nuisance and a potential safety hazard. However, if the rest of the car is in good condition (engine, transmission, suspension, and electrical systems), it can still be a fantastic vehicle.
**The 535i (N54) is the more exciting choice** for performance enthusiasts, but it requires more maintenance due to its twin-turbo setup. The **528i (N52) is more reliable and efficient**, making it a better daily driver if you don t need extreme power.

### **Recommendation**
1. **If the seat track is only slightly worn:**- Proceed with the purchase **only if** the rest of the car checks out (service records, no major electrical issues, transmission in good shape).
- **Budget $300 $600** for seat track replacement before buying or shortly after.
- Consider negotiating the price **$1,000 $2,000 lower** to account for the seat issue.
2. **If the seat track is severely degraded (loose, noisy, or seized):**- **Walk away** unless you re willing to pay full price for a car that will require immediate repairs.
- Look for an alternative E60 with a **replaced seat track** or a different luxury sedan (e.g., Audi A6, Mercedes E-Class) if seat comfort is a priority.
3. **Before purchasing:** - **Get a pre-purchase inspection (PPI)** from a BMW specialist to assess:- Transmission condition.
- Electrical system health.
- Suspension and steering components.
- Engine and exhaust integrity.
- **Verify service history**, especially for:- Transmission fluid changes.
- Cooling system maintenance.
- Brake and suspension replacements.
- **Test drive thoroughly**, paying attention to:- Seat movement (does it rattle or shift unexpectedly?).
- Transmission shifts (smooth or jerky?).
- Electrical functions (windows, locks, infotainment).
4. **If you decide to buy:**- **Replace the seat track immediately** to avoid further annoyance.
- **Prioritize maintenance** stick to BMW-approved fluids and parts where possible.
- **Consider a warranty** (e.g., CarCo, Endurance) to cover unexpected repairs in the first year.
**Final Verdict:**The E60 is a **fantastic car for the right buyer** someone who values driving pleasure over perfection and is prepared for occasional repairs. If the seat track issue is the only major flaw and the rest of the car is solid, it can be a **great long-term investment**. However, if you re sensitive to minor inconveniences or unwilling to spend extra on repairs, look elsewhere or negotiate aggressively for a fully serviceable example.
