What does service B consist of on Mercedes clk 500?

Description: Oil change (synthetic), brake inspection, tire rotation (can't rotate these, they are staggered), top off all fluids, reset maintenance indicator, replace engine filter (two), a/c dust filter (carbon air filter), and remote batteries (never had them do this).

Perform brake flush. (this is optional. My shop said I didn't need it so often)

Timeframe: 2.5 - 3 hours

Rough cost would be $300 - $500 depending on what all needs to be replaced and who does it. Dealership will likely be the higher end or more. Local MB specialist will likely be on the lower.
