It really depends on what type of information the police have to work with. If they have a good reliable description of the car that hit yours, they will scour the town looking for like colored vehicles with damage to whatever area they determine has hit on their vehicle. Witnesses would be good, especially if they have description of driver, passengers or tag number is always helpful. Otherwise, there is not much the police can go on. It also depends upon weither it occurs on a parking lot or not. Parking lot accidents regardless of amount of damage will be considered minor accidents, whereas accidents on the street are viewed more serious and reports are compiled and sent to DMV, I believe. If all the officer has to go on is the color of the car then the only other thing the officer can do is supply the victim with a change of information showing their insurance that they have reported the crime which goes a long way in getting repairs to victims vehicle. Hope this helps.
