Hi, sorry for the wait. My name isXXXXX service on the SL is about a 2.5 hour service and includes an oil and filter change and a cabin air filter replacement and a wiper blade replacement if needed. It also includes a comprehensive inspection of the vehicle from front to back. I would expect the total charge for the B service to be in the $475 range using a $110 per hour labor rate. The price includes new wiper blades.
