I am a lawyer in CT and practice in the area of the law.  You should get the insurance company the estimates and then determine what they will give you in terms of money for the damages.  then you may take the car anywhere you want and have the insurance company issue you a check.  if you disagree with the estimate, take the car to your own garage for an estimate and get the insurance company to come up higher.   You ultimately can choose where thre car is serviced.  however, the idea is to get it fixed right.
