THe best place tri state to get a car washed is Classic shine in greenwich, ct 5 minutes over the westchester ny boarder
the owners name is anthony tell him jared levine sent you. he is a friend of my families.
you will see some serious rides there on weekends... i'd call in advance if you can just to not chance weather he'd be ther.
another great place for a quick wash is Puffs Auto Salon in mount kisco. he used to be in armonk but is now on lexington ave. Very good hand car wash no rollers...high end cars i think its under 30 bucks too.
if your going for quality go to classic shine
if you want more speed but still quality go to puff.
tell both of them Jared Levine sent you and they will take care of you.
