what car is the other car? very expesinve car? if me and my cheap runner, 黑㾗能用手卒甩, i will just tell you to be careful and drive off. fixing need time, i dont' have time.
bad luck....but since there is no photo, we can not judge is it really so bad that need to repair, from your description, i will offer the other car owner $3000 and max $5000 on the spot if i can see the "有兩點卒不掉的圓㾗 約3MM直徑".
to be honest, if i am the bmw owner, unless it is very bad, i wont' want my bumper fully repainted even if it is free, i rather take a few thousand cash from you to buy some nice food to eat and jsut drive with the 兩點卒不掉的圓㾗 約3MM直徑
$18k should be under no claim protection for most policy? or does it not include paying third party damages?
you have no choice but let the insurance company pay for it in this case, since the amount is not resonble. or you can try to talk to him and say come on? just take it to outside garage fix it, whatever the cost you pay $2000 more as his compenstation, doubt it will be over $4000 if fixed outside and he gets $2000 cash and ask him if he really want his brand new car to have a crashed repair record logged with BMW?
