I have a long time (17 year) Viper tech here that works on my GTs and he does a great job. I know Chuck very well. He was a Dodge dealer and his family dealership got cancelled in the meltdown. It was one of the oldest in the U S.
He is one the the nicest, most honest guys you will ever meet. I hope SRT makes him an authorized dealer again. There is an interesting DvD on his family operation floating around.
