I know how you feel...the other day I was doing some basic maintanence, prosport guage, and xm radio on the ms6, and everything was going wrong...and Im not a car newb by a long shot. That night I felt like crap about the car, just not excited about the car at all. The very next day, we had a blizzard here and some d-bag cabbie lost control and came across my nose twice. The 6 handled amazingly well! Never lost grip, abs kicked in, traction contoll kicked in and allowed me to slow and swerve into the next lane without any drama. In any of my past cars I would have fish-tailed from that maneuver.
Moral of the story, when your feeling down about the car, just go drive it and give it a chance to put a smile back on your face.
