I would go to a physician first, before simply hitting a Chiropractor...you need to find out if there is more than just minor muscle damage\\displaced joints. You probably will be sore for a few days, but I would seriously go to a doctor first...get x-rays if necessary, and then visit a Chiropractor if warrented.
Did you get the other driver's information? This is something that should ALWAYS be done, because if he was at fault, then he needs to cover your medical\\vehicle expenses. Course, if he 'just' bought the car, the dealer would be covering this accident (the new owner would have 10 days to get it properly insured), but it is still very important that YOU have his information, so he can't just go to the dealer and get HIS end covered...you need to be covered as well.
