New to the forum with a question.  Are there any rules to where people can park in the neighborhoods?  We are around a few houses who own several cars (up to 5 in one house) and I’m afraid our home along with others in the area have lost their curb appeal. 

We keep our cars kept in the garage and try to upkeep our lawn, but it's pointless when cars are parked in front of our house all the time.  I feel it's making the area less attractive with cars blocking other people’s homes in addition to oil marks and stains all along the streets.

 Am I being too picky?  Is there anything that can be done?
