What reviewers say

Reviewers agree the GLC Coupé has a smart, well-equipped interior and strong performance, but costs more than the regular GLC while giving up boot space and rear headroom. Opinions on the drive differ: Auto Express found it refined and comfortable, while What Car? found the ride uncomfortable and the BMW X4 more fun.
