Took my 20-year-old car, normally in very good shape, into dealer for oil and filter change, expecting they would do the usual check of other fluids. I asked dealer to check brakes as well, and they found leaky wheel cylinders, but they didn't check brake fluid or they would have noticed it needed to be flushed. The dealer also didn't notice an oil leak and a transmission fluid leak right at the drain plug. I appreciate Car Care Service going the extra mile and focusing on prevention as opposed to waiting until things got bad and then I would have to bring the car in for a big repair.
