### Pros and Cons of Buying a Mitsubishi TM20RAH
The **Mitsubishi TM20RAH** is a compact, rear-wheel-drive sedan produced between 2003 and 2008. It was sold in some markets under the **Mitsubishi Lancer Evolution** name (specifically the **Evolution IX**) in others. Below is a detailed breakdown of its advantages and disadvantages.
---
### **Pros**
1. **Strong Performance and Handling**
The TM20RAH is based on the Lancer Evolution platform, meaning it retains the sporty, agile handling that made the Evolution series famous. It features a rear-wheel-drive layout, precise steering, and a well-tuned suspension, making it enjoyable to drive on both roads and light tracks.
2. **Reliable Engine Options**
The TM20RAH was available with a **2.0-liter 4G63 engine** (naturally aspirated or turbocharged in some markets). The turbocharged version (when available) produces around **220 240 horsepower**, providing solid acceleration for its class. The naturally aspirated version is more fuel-efficient but still capable of decent performance.
3. **Durable and Well-Built**
Mitsubishi s engineering in the Evolution series was known for durability, and the TM20RAH carries that reputation. Many examples have lasted well beyond 200,000 miles with proper maintenance, especially the turbocharged models if they were well-tuned.
4. **Good Resale Value (for Classics)**
As a rare and sought-after compact hot hatch/sedan, the TM20RAH holds its value better than many contemporaries. Enthusiasts and collectors appreciate its blend of performance and practicality, which keeps demand steady.
5. **Practicality for Its Size**
Despite its sporty nature, the TM20RAH offers reasonable cargo space (around 12 14 cubic feet) and a comfortable interior for its class. The rear seats fold flat, making it useful for light adventures or road trips.
6. **Aftermarket Support**
The TM20RAH shares parts and tuning potential with the Lancer Evolution, meaning there is a strong aftermarket presence. Upgrades like exhausts, suspension kits, and engine tuning are widely available, allowing owners to further enhance performance.
7. **Affordable to Purchase (Used Market)**
Depending on condition and location, a used TM20RAH can be found for **$5,000 $12,000**, making it an attractive option for those seeking a fun, capable used car without breaking the bank.
8. **Fun to Drive**
The TM20RAH s understeer-heavy but forgiving nature, coupled with its sharp steering and engaging exhaust note (especially the turbo models), makes it a joy to drive on twisty roads.

### **Cons**
1. **Turbocharged Models Can Be Problematic**
While the turbocharged 4G63 engines are powerful, they are notorious for **oil consumption issues**, **turbo failures**, and **valve float** at high RPMs if not properly maintained. Many owners report excessive oil burns, requiring frequent top-ups. Some models may have **internal engine damage** if neglected.
2. **Reliability Concerns with Age**
Like most cars from this era, the TM20RAH is now **well past its prime**, and many components (e.g., suspension, electrical systems, and transmissions) are wearing out. Rust can be an issue in regions with harsh winters or salted roads.
3. **Limited Modern Safety Features**
The TM20RAH lacks modern safety standards such as **stability control, advanced airbag systems, or electronic stability programs**. While it handles well, it would not perform as safely in a severe crash compared to modern vehicles.
4. **Fuel Economy is Poor for Its Class**
The turbocharged version gets around **18 22 MPG**, while the naturally aspirated model is slightly better at **25 30 MPG**. This is worse than many modern compact cars, which average **30 40 MPG** or more.
5. **Maintenance Can Be Expensive**
Parts for a 20-year-old car can be costly, especially if they are no longer in production. Some aftermarket parts may not fit perfectly, and labor costs add up over time.
6. **Comfort and Ride Quality**
The TM20RAH prioritizes sportiness over comfort. The stiff suspension and limited sound insulation mean it can be **noisy and jarring** on rough roads compared to modern sedans.
7. **Limited Availability of New Parts**
While the aftermarket helps, some original parts (e.g., specific suspension components, wiring harnesses) may be difficult to source, increasing repair costs.
8. **Not Ideal for Heavy Daily Use**
The turbocharged models, in particular, are not suited for **high-mileage daily driving** without significant maintenance. The oil consumption and potential for internal wear make them better suited for **weekend driving or track use**.

### **Conclusion**
The **Mitsubishi TM20RAH** is a fantastic choice if you are looking for a **fun, engaging, and capable used car** that offers a blend of performance and practicality. It is particularly appealing to enthusiasts who appreciate **RWD handling, turbocharged power, and a cult following**. However, it is **not a plug-and-play daily driver** it requires **regular maintenance, especially for turbocharged models**, and may not be as reliable or safe as modern alternatives.
If you are **mechanically inclined, willing to invest in upkeep, and prioritize driving enjoyment over convenience**, the TM20RAH is an excellent purchase. On the other hand, if you need a **low-maintenance, safe, and fuel-efficient** vehicle, a modern compact sedan or hatchback would be a better choice.

- You plan to **drive it moderately** (e.g., weekends, track days) rather than daily.
- You enjoy **tuning and modifying** your car.
