First off , glad you are okay.
As far as the suv...
Could it be a mercedes?
You can do a couple things...
1. Look on google maps around your neighborhood to see if any vehicles around your house kinda match the description .
2. Keep put a go pro somewhere to take a time lapse picture to see all the vehicles that come through the street.
If you said this has been the second time, then that person must live around there somewhere and is bound to take that route again (human habits of comfortless)
Good luck
