Wichita location has terrible service. Brought my Mercedes in for repairs related to sound coming from hood. They charged me $1,500 to fix in conjunction with maintenance I did not request. Next day sound still exists. Brought car back to have them reevaluate the issue. Charged me another $300 for a separate diagnosis and repair. Smdh. Frustrating. Thank you Welser of Wichita, Kansas. (Super unsatisfied customer).
