My GL450 4MATIC had issues with the Cup warmer/cooler, front cigarette lighter, rear cigarette lighter, and glove box light out. I made it clear if they could not save me money vs what Mercedes would do, then we should shake hands and not do business. Honest-1 took care of the issues in short order and did not hit me over the head with charges. I will be returning to them for other services needed on both the GL450 and E350 4MATIC. Peace and Blessings
