I would like to expand on Kirk's recommendation to consider DIY on your oil change and brake flush.
I posted a most excellent
Brake Flush DIY here on this forum. I wrote it from the perspective of someone with no clue [me]. There are other excellent Boxster flush DIYs on the internet. [I am proud of mine, however] and I concluded that while the oil drains during my oil change, I can flush the brakes, all in about an hour or so [getting the car on stands and the wheels on/off is half the time] at a savings of about $300. Its easy work if you are interested.
