After a negative experience with the service center I appreciated the service center manager, Patrick, calling me and going over the service that was done on my AMG GLE 53. Personal service is primary in my business, pharmacy, and him reaching out was important. I will continue to use MB of Chesterfield service center in the future and give them another chance.
