Overall: I went to a Cassidy store to have my wheel assemblies balanced and have the oil and filter changed.
they listen to my specific requirements, I tried to inform them of the problem and they ignored me. They also didn't put the correct amount of oil in may car (not life threatening ) . I returned to my home town on unbalanced wheels. When spoke to an owner of the company who was unwilling admit any liablity satisfy a customer. I will never shop at that store and be sure to inform the BMW dealership in Chicago not to recommend them not to refer any of there clients. I have since had the vehicle repaired at another reputable tire outlet using the same verbal instructions, this time with satisfactory results. They also topped of the oil for me which was over a quart low (again not life threatening).
