Review:
Performance:

• Smooth and refined acceleration with ample low-end torque. The 9-speed transmission shifts seamlessly but may hesitate in low-speed maneuvers.
• 4MATIC AWD ensures confident handling in adverse conditions, though the focus is on comfort over sportiness. Suspension (front/rear multilink) prioritizes a plush ride.

Interior & Tech:

• Luxury: High-quality materials, quiet cabin, and ergonomic design. Optional AMG Line adds sporty touches.
• Tech: COMAND interface criticized for complexity; touchpad controller can be distracting. Optional 8.4-inch screen improves usability.

Practicality:

• Spacious front seats, but rear legroom is tighter than rivals like the Audi Q5. Cargo space is competitive.
• Reliable for the segment, though maintenance costs align with luxury brands. Watch for minor electrical issues.

Safety:

• IIHS Top Safety Pick (with optional LED headlights). Standard safety tech praised, though advanced features require packages.

Competitors:

• BMW X3: Sportier handling but firmer ride.
• Audi Q5: Balanced performance, virtual cockpit advantage.
• Lexus NX: More reliable, less refined.

Pricing (2017 MSRP): ~$41,895 (base), rising with options.

Pros:

• Upscale, quiet interior.
• Comfort-oriented ride quality.
• Strong turbo engine and smooth transmission.

Cons:

• Cumbersome infotainment system.
• Expensive optional packages.
• Average rear-seat space.

Verdict:
The 2017 GLC 300 4MATIC excels as a comfortable, luxurious compact SUV with robust tech and safety offerings. Ideal for buyers prioritizing refinement over sportiness, though option costs add up quickly.
