I wouldn't tell either insurance company you were at fault. Just tell them what happened, and let them hammer out who's at-fault. (ex. you had your blinker on checked to make a lane change, porsche came out of no where and a collision took place.)
Good luck. And please tell me you have more than $5,000 worth of insurance for property damage.
