Hi Lynn,
sorry you had such a dysmal week....I do hope it does get better.
I agree that you should talk directly to the boss in the dealership. The middleman usually just goes by his "book of SOPs".
As far as far as the bushings go I would double check the tire pressures when you get your car back. With the Xfires low profile tires, overinflation can put quite a bit of extra stress in the linkage joints. The wheels on my baby where all quite a few pounds over the recommended pressures.
But 2 weeks is still very very short time.....of course I don't know what the roads in DC are like ;-)
