Suspicious Vehicle Observed in Preston Hollow

This afternoon around 1:30-2:00 pm two Preston Hollow Homeowners' observed a small silver vehicle like a Honda or Hyundai driving back and forth three times in the cul-de-sac in front of their home at 329 Forest Wood Ct. The driver would approach from the South then slow down in front of our house. We walked out front to the sidewalk to get a tag number, but the vehicle quickly sped away each time. The vehicle's windows were tinted so we could not identify the driver…there did not appear to be a passenger in the car.  One of the homeowners' drove around the neighborhood right after these observations but did not see the vehicle anymore.
