Same for me... I've used ramps for years and years and they work great for the Boxster oil change. Much quicker than jacking the car and positioning stands. I also back onto a slope so that the car is level when it is ramped. Very slick.
+1 for ramps. No problem getting the rear up on ramps even with my lowered car. In addition to everything the others have said, they feel safer when I'm under the car versus jack stands. Also good for adjusting suspension while it is under load.
