Dropped my Z4 off at the dealership to have some warranty work done and was wondering if there is any preventative maintenance I should insist BMW fix before anything actually breaks. The car has 76k miles; almost all are high way. Radiator was replaced about 10k ago and the tech has already informed me that the belts need to be replaced. Plus I complained there was a slight whistling coming from the upper window region and was told that the seals need to be replaced/adjusted and was quoted 600 for this
: does this seem a little outrageous to anyone?
