You have to be very careful with GEICO, they are well known for getting lower rates for customers by cutting the coverage, they also are known for giving auto repair shops a very hard time if they try to use anything but used body parts, there are 2 body shops near me that in the past (may or may not still be the policy) that would not take any insurance work if it was for GEICO due to the issues of dealing with them.
There is a saying in the insurance industry, GEICO takes the most customers from the insurance carriers and the other insurance carriers get the most customers that have been with GEICO lol
