Just got my model 3 AWD- non P llast week 8/4/18 and under 200 miles. This happened in San Francisco Golden Gate Park and I was stopped stationary at a stop sign and this fool with his 2003 BMW wagon trying to make a right turn or whatever hits me with his front left bumper. So angry... I called my State Farm insurance company and they told me to call his insurance company (AAA) first to file a claim. I called to file a claim and am suppose to hear back from a claims adjuster on Monday. . Is this a good way to go about this or should I let my insurance fight for me? I'm afraid AAA might low ball me, sending me to any Joe Schmoe body shop. I'm also afraid some of the sensors might be damaged. Also I'm not sure if I can file for diminishing value??
