Got my car back Thursday, they did a software update which seems as though it's improved the sound while on Blutooth Audio, there was definitely a distortion issue with the lower frequencies before the update which seems to now be better.
They said by doing the update it would update everything on the car which was good (normally around $170 in think)
They also fixed up the Hatchback Handle, it was coming unclipped when you used it.
Got a nice loan car for the night/day - C180 Coupe, cream/white Leather..very nice..but I prefer my 250
