Know this... A luxury car is expensive to fix because of a few things...
1. Actual quality and complexity in the parts/procedures to repair.
2. Markup of parts due to lack of rebuildable spares availability, and/or Brand name ALONE.
3. You fail to realize that you could change your oil and plugs on your own... and not have to succumb to the stealership for routine/preventative maintenance.
