#### **Cons:**1. **Age and Wear** This is a **2001 model**, meaning it has been in service for over two decades. Older vehicles are more prone to mechanical wear, including engine issues, transmission wear, and electrical failures. The **carb plunger** (a common problem in older Bombardier 700s) suggests potential fuel system or intake issues that may require attention.
2. **Potential for Hidden Mechanical Problems** At this age, the vehicle may have accumulated significant mileage or neglect. Common issues in older 700s include:
- **Engine wear** (piston rings, valves, or timing issues)
- **Transmission problems** (slipping gears, fluid leaks)
- **Suspension degradation** (worn shocks, bushings, or control arms)
- **Electrical gremlins** (failing sensors, wiring issues)
- **Rust or frame damage** (especially if stored outdoors)
3. **Fuel System Issues** The mention of a **"carb plunger"** (likely referring to a carburetor or fuel injection problem) is a red flag. Older Bombardier 700s often suffer from:
- **Clogged or failing carburetors** (if equipped)
- **Fuel pump failures**
- **Intake manifold leaks**
- **Electronic fuel injection (EFI) malfunctions** (if applicable)
These issues can lead to poor performance, stalling, or difficulty starting.
4. **High Maintenance Costs** Older vehicles require more frequent and costly maintenance. Parts may be expensive, and labor costs add up, especially if the vehicle has been poorly maintained.
5. **Depreciation** A 2001 model is well past its prime, and while Bombardier 700s hold value better than many, it will still depreciate significantly compared to newer models.
6. **Potential for Modding Costs** If the buyer plans to upgrade components (engine, suspension, exhaust), the cost of parts and labor can be substantial, especially if the vehicle is not already in good condition.
7. **Reliability Concerns** While some 700s last for decades with proper care, others develop chronic issues. Without a **full service history**, it s difficult to know the true condition of the vehicle.
8. **Market Availability of Parts** While parts are still available, some components (especially for older models) may become harder to find over time, increasing repair costs.

### **Conclusion:**Buying a **2001 Bombardier 707 Quest 500 with a carb plunger issue** is a **high-risk, high-reward** purchase. The vehicle has strong potential as a **reliable, capable off-road machine** if it is **well-maintained, thoroughly inspected, and repaired**. However, the age of the model and the **fuel system problem** (carb plunger) suggest that **significant work may be required** before it is road-ready.
If you are **mechanically inclined, have a budget for repairs, and can afford to invest time in restoring it**, this could be a **great project vehicle** with long-term value. However, if you are looking for a **plug-and-play, low-maintenance machine**, a **newer or better-condition Bombardier 700 (or even a different brand like Polaris Ranger, Can-Am Maverick, or Arctic Cat)** would be a safer choice.
---
### **Recommendation:**1. **Get a Full Pre-Purchase Inspection (PPI)** Hire a **trusted mechanic or Bombardier specialist** to thoroughly inspect the engine, transmission, fuel system, suspension, and electrical components. This should cost **$200 $500** but could save thousands in unexpected repairs.
2. **Verify the Carb Plunger Issue** If the problem is a **carburetor or fuel injection malfunction**, determine whether it is a **minor fix (cleaned carb, replaced jets) or a major overhaul (new carb, fuel pump, or EFI rebuild)**. If the cost exceeds **$1,000 $1,500**, reconsider the purchase.
3. **Check Service History** A **complete service record** (oil changes, valve adjustments, transmission flushes, etc.) is crucial. Without it, you re buying a **lottery ticket** some older 700s run forever, while others are ticking time bombs.
4. **Budget for Repairs** If you decide to buy, **set aside at least $3,000 $5,000** for immediate repairs. Additional funds should be allocated for **ongoing maintenance** (e.g., suspension refresh, engine rebuild if needed).
