My $.02, Be nothing but a gentleman, and don't trying to win the world, talk to a lawyer, get what you deserve (car repairs, decreased value payment, any pain you might be in).
muncipalitys have huge insurance companys to work for them in lawsuits they are a pain in the ass to deal with,hence talk to a lawyer, and cops remember people who try to screw them over and be jerks, so do their colleages, and yes it was his fault, and they will fix your car, and you if need be.
But the next time you are running 10 over the posted, he might say "that guy was pretty cool when i hit him" or he might say, that guys a jerk and tried to screw me and the PD hardcore, lets give him a ticket.
Don't ask me how i know, i just do.
Keep records of everything done to the car, pics, repairs, so if you do sell it, you can show a patencial buyer what happen and why car fax shows and accident. I bought an impala ss that was wrecked, car fax showed totaled, but when he gave me all the paperwork and pics, it wasn't that bad, i bought it without hesitation, so it sometimes can help.
Good luck sir.
