ouch, looks really familiar. same thing happened to me a few months ago while my g/f was driving my accord and went right underneath a trucks trailer hitch. Good thing the car is lowered because it just missed the radiator and radiator support/tie bars. It still came out to be around $800 though and the radiator,bumper,a/c, etc didnt even have to be replaced.. so i wouldnt be surprised if yours was $2k or more. but good luck with it man
