Comparison Overview

Choosing between the 2025 Buick Enclave and the 2025 Mercedes-Benz GLC-Class presents a classic dilemma: do you prioritize spacious luxury or efficient refinement? If sheer size matters, the Enclave is significantly longer at 207.6 inches compared to the GLC-Class's 185.7 inches, which translates to more interior room.

Power delivery is another key difference; the Enclave offers a punchier 328 hp and 326 lb-ft of torque versus the GLC-Class’s 255 hp. The initial investment also favors the Buick, starting at $45,100 versus the Mercedes’ $49,250 MSRP, creating a clear cost consideration for budget-conscious buyers needing a capable three-row alternative.
