how do i sue for damage to a vehicle

If the damages are less than $10,000, you can (and should) file the case in small claims court. If you are seeking recovery from the at-fault driver, you can only sue the driver. You cannot sue the insurance company directly. But just be aware that, once you file the suit, the insurance compnay is going to hire an attorney to represent their driver and will probably request a jury trial. So, you will have to deal with all of that. Nevetheless, since small claims court has very relaxed and informal procedures, and since the formal rules of evidnece do not apply, this remains your best option. Another option would be to put the claim through your insurance company if you have the proper coverage.  You may have to pay your deductible, but you will get your car fixed and back on the road.  Then let your insurance compnay worry about going after the other side for reimbursement. if they are successful in getting reimbursed, then your insurance company will refund your deductible.
