Bottom Line
The Mercedes-Benz GL-Class wins on composite reliability across TÜV, ADAC, NHTSA, and DVSA MOT data — typically a sign of lower ownership risk and fewer recurring failure modes at age. The other car isn't necessarily wrong; check its issue list and price-to-condition ratio before deciding.
