Car hit while parked, worth pursuing?

[Pgtips]

Looking at your pictures of damage to both vehicles i can't see any damage on your black car at 24" high where there's black paint on the silver car at that height so might just be a total coincidence & would be very cautious about going & knocking on someones door & accusing them of hit & run.
Personally i would report it to the police & inform them of your suspicions & let them go knock on his/her door
