Review LEXUS Sport Sunroof Track Assembly Oem Beige fits IS300 IS350 2014–2020

The **Lexus IS300/IS350 Sport (Model Code: 43-00073, VIN Range: JTD20-202073, 2017 Model Year)** represents the pinnacle of refined performance, blending Lexus s signature luxury with the exhilarating precision of a high-performance sedan. Engineered for those who demand both elegance and dynamic capability, this model is a masterclass in engineering, featuring a **2.0-liter turbocharged inline-4 engine (for the IS300) or a 3.5-liter twin-turbocharged V6 (for the IS350)**, both delivering an impressive power output of **268 horsepower and 272 lb-ft of torque** (IS300) and **302 horsepower and 302 lb-ft of torque** (IS350), respectively. The V6 variant, in particular, is a standout, offering a seamless and linear power delivery that transforms the IS350 into a true grand tourer with sporty intent, all while maintaining Lexus s reputation for quiet, smooth operation. Paired with an **8-speed automatic transmission** and **Lexus Sport Shift** (for the IS350), this powertrain ensures razor-sharp gear shifts and responsive acceleration, whether cruising on a winding coastal road or navigating a spirited overtake.

The **IS300/IS350 Sport** is built upon Lexus s **TNG-A platform**, a rigid yet compliant chassis that enhances handling dynamics while absorbing road imperfections with ease. Standard **adaptive variable suspension (AVS)** with **adaptive damping** allows the driver to switch between **Comfort, Normal, and Sport** modes, tailoring the ride quality to the driving conditions. For those who crave even more engagement, the **IS350 Sport** comes equipped with **Lexus Dynamic Radar Cruise Control (DRCC)** and **Lexus Safety System 2.0**, which includes features like **pre-collision braking, lane departure alert, and adaptive high-beam headlights**, ensuring both safety and confidence on the road. The **Sport Package** further elevates the driving experience with **19-inch alloy wheels**, **sport-tuned exhaust**, and **sport-tuned suspension**, while the **Track Package** (available on select trims) takes performance to the next level with **stiffer suspension tuning, larger brake rotors (330mm front, 320mm rear), and a limited-slip differential**, making it a formidable track weapon.

Inside, the IS300/IS350 Sport exudes **premium sophistication**, with a **luxurious cabin** featuring **full-leather seating**, **heated and ventilated front seats**, and **available ventilated rear seats** for optimal comfort during long journeys. The **12.3-inch touchscreen infotainment system** (with optional **12.3-inch digital gauge cluster**) integrates seamlessly with **Apple CarPlay, Android Auto, and Lexus Enform**, providing intuitive connectivity and entertainment options. The **steering wheel-mounted controls** and **ambient lighting** (available in multiple colors) add to the bespoke feel, while the **available **12-speaker Harman Kardon premium audio system** delivers immersive sound quality that rivals dedicated car audio systems. The **sunroof** in this model is not just a luxury feature but a **panoramic glass sunroof** that maximizes natural light and ventilation, enhancing the open, airy feel of the cabin.

For those who appreciate both style and function, the **IS300/IS350 Sport** offers a **sleek, aerodynamic design** with **Lexus s signature "coke bottle" body style**, characterized by **sharp creases, a bold front grille, and LED headlights** (standard on IS350) that project a commanding presence. The **19-inch or 20-inch alloy wheels** (depending on configuration) complement the sporty stance, while the **sport-tuned exhaust** adds a subtle yet satisfying growl, reinforcing the car s performance credentials. Whether parked in a high-end showroom or cruising along a scenic highway, this Lexus commands attention without compromising on the understated elegance that defines the brand.

Ultimately, the **2017 Lexus IS300/IS350 Sport (43-00073)** is a **versatile grand tourer** that seamlessly transitions from daily driver to weekend track star. Whether you re navigating city streets, merging onto the highway, or pushing the limits at a racetrack, this model delivers **uncompromising performance, unmatched refinement, and a level of luxury that sets it apart**. With its **turbocharged or twin-turbocharged powertrain, advanced safety features, and meticulously crafted interior**, it embodies Lexus s commitment to blending **Japanese craftsmanship with cutting-edge technology**, making it a **timeless choice for discerning drivers who refuse to settle for anything less than excellence**.

### **Pros and Cons of Buying a 2017 Lexus IS300/IS350 Sport with Sunroof (VIN: 43-00073)**

#### **Pros**

1. **Reliability and Reputation**

Lexus is known for its durability and long-term dependability, especially in the IS series. The 2017 models come with a strong track record for engine longevity, provided they were well-maintained. The 2.0L turbocharged engine (IS300) and 3.5L V6 (IS350) are both well-regarded for their smooth operation and low failure rates compared to many competitors.

2. **Performance and Handling**

- The **IS300** offers a turbocharged 2.0L inline-4 engine producing **241 hp** and **270 lb-ft of torque**, providing quick acceleration and a sporty driving experience.

- The **IS350** features a **3.5L V6** generating **306 hp** and **269 lb-ft of torque**, offering more power and a more refined, premium feel. Both models come with Lexus s **Direct Shift-DCT** (dual-clutch automatic) transmission, which is smooth and efficient, though some drivers prefer a traditional automatic.

- The **Sport Package** enhances handling with sport-tuned suspension, quicker steering, and a sport-tuned exhaust, making the car more engaging to drive.

- The **sunroof** adds comfort and a more premium feel, especially on long drives.

3. **Luxury and Comfort**

Lexus IS models are built on a Toyota platform but offer a more upscale interior than most Toyota sedans. The cabin is quiet, well-insulated, and features high-quality materials, including leather seats (standard on higher trims), ambient lighting, and a refined infotainment system (if equipped with the **Track Package**, which includes a **10.3-inch touchscreen** and **Lexus Enform** connectivity).

4. **Track Package Benefits**

The **Track Package** is a significant upgrade for enthusiasts, offering:

- **Lowered suspension** for improved handling.

- **Stiffer bushings** and **sport-tuned shocks** for better cornering.

- **Brembo brakes** (larger rotors and high-performance pads) for improved stopping power.

- **Sport-tuned exhaust** for a more aggressive sound.

- **19-inch alloy wheels** (instead of the standard 18-inch) for a sportier look.

- **Redesigned front bumper and side skirts** for an aggressive stance.

This package makes the IS350 particularly well-suited for track use or spirited driving on the road.

5. **Resale Value**

Lexus vehicles hold their value well, and the IS350 in particular has strong resale potential due to its popularity and reliability. A well-maintained 2017 model should retain a significant portion of its value over time.

6. **Low Maintenance Costs**

Lexus dealerships are known for being less aggressive with upselling repairs compared to some luxury brands. Parts are widely available, and the turbocharged 2.0L engine (IS300) and V6 (IS350) are relatively inexpensive to maintain compared to high-performance or exotic cars.

7. **Safety Features**

The 2017 IS comes standard with Lexus Safety System 2.0, which includes:

- **Pre-Collision System with Pedestrian Detection**

- **Lane Departure Alert with Steering Assist**

- **Dynamic Radar Cruise Control**

- **Automatic High Beams**

- **Blind Spot Monitor with Rear Cross-Traffic Alert**

These features provide peace of mind for daily driving.

#### **Cons**

1. **Turbocharged Engine Concerns (IS300)**

- The **2.0L turbocharged engine** in the IS300 is more complex than a naturally aspirated engine and requires proper maintenance to avoid issues like **turbo lag, oil consumption, or carbon buildup**.

- If the car was not regularly serviced with **high-quality synthetic oil** (e.g., Lexus recommended 0W-20 or 5W-30), there may be **carbon deposits** in the intake valves, leading to rough idle or reduced power.

- **Oil leaks** from the turbo or valve cover gasket can occur if the car was not well-maintained.

2. **Transmission Issues (DCT)**

- The **Direct Shift-DCT (dual-clutch automatic)** is smooth but can be **less responsive** than a traditional automatic or a manual transmission.

- Some owners report **jerky shifts** or **delayed engagement**, though this is more common in earlier models. A well-maintained DCT should last the life of the car.

- **Clutch wear** is a potential long-term concern, though Lexus DCTs are generally reliable if serviced properly.

3. **V6 Engine Reliability (IS350)**

- While the **3.5L V6** is robust, it is **not as efficient as the turbocharged 2.0L** in terms of fuel economy. Expect around **20-22 MPG city / 28-32 MPG highway** (real-world numbers may vary).

- **Valvetronic throttle issues** (where the throttle body can stick) have been reported in some Lexus V6 models, though this is rare in the IS350.

- **Timing chain stretch** is a theoretical long-term concern (though uncommon in the IS350), as Lexus V6s traditionally use chains rather than belts.

4. **Track Package Limitations**

- While the **Track Package** significantly improves handling, it is **not a full race car setup**. The suspension is still tuned for **road use**, not extreme track abuse.

- **Brakes** are improved but may still struggle with repeated hard braking on a track.

- **Tires** (likely standard all-season or summer tires) may not be optimal for high-performance driving without upgrades.

5. **Infotainment System (If Not Upgraded)**

- The **standard infotainment system** (if not part of the Track Package) is **basic by modern standards**, with a smaller screen and slower response times compared to newer Lexus models or competitors like the BMW 3 Series.

- **Bluetooth connectivity** may be limited, and **Apple CarPlay/Android Auto** were not standard in 2017 (though aftermarket solutions exist).

6. **Depreciation**

- While Lexus holds value well, luxury sedans (even reliable ones) still depreciate. A 2017 IS350 may have lost **30-40% of its original value** by now, depending on mileage and condition.

- If you plan to keep it long-term, this is less of a concern, but if you need to sell soon, depreciation is a factor.

7. **Potential Hidden Issues**

- **Oil leaks** (valve cover gasket, oil filter housing gasket) are common in some Lexus models, though not exclusive to the IS series.

- **Exhaust manifold cracks** (especially on the V6) can occur with high mileage, though they are usually repairable.

- **Electrical gremlins** (e.g., sensor failures, infotainment glitches) can be frustrating but are not unique to this car.

- **Sunroof leaks** can develop over time if the seals degrade, leading to water damage in the cabin.

8. **Fuel Economy Trade-offs**

- The **IS300 (turbo)** is more fuel-efficient ( 25-30 MPG combined) than the **IS350 (V6, 20-25 MPG combined)**. If fuel efficiency is a priority, the IS300 may be the better choice.

- Neither model is particularly efficient compared to modern hybrids or turbocharged non-luxury cars.

9. **Maintenance Costs Over Time**

- While Lexus is cheap to maintain initially, **specialized repairs** (e.g., turbocharger replacement, DCT servicing) can add up if issues arise.

- **Track Package upgrades** (e.g., aftermarket suspension, tires, brakes) may be needed for serious enthusiasts, increasing long-term costs.

10. **Resale Market Competition**

- The **IS350 Track** is a popular model, meaning there may be **many competitors** in the used market. Pricing can be competitive, and you may need to negotiate hard for the best deal.

- **BMW 330i/340i, Audi A4, and Genesis G70** are direct competitors and may offer similar performance at a lower price if well-maintained.

---

### **Conclusion**

The **2017 Lexus IS300/IS350 Sport with Sunroof and Track Package (VIN: 43-00073)** is an **excellent choice** for buyers who prioritize **reliability, luxury, and sporty driving** without the high maintenance costs of a German luxury car. The **Track Package** makes it one of the best **track-capable sedans** in its class
