SKY7 flew over the hole on Stockbridge Avenue Saturday afternoon where it was empty.
But it is still a mystery as to what is exactly inside the car, if anything.
However, cadaver dogs did get a number of hits.
Investigators think the car may have been buried since the 1990s.

The car is reportedly an early 90s Mercedes Benz model convertible that was reported stolen in September 1992, according to Palo Alto police records. No plates or vehicle identification number information have been released at this time.
The discovery has put the focus on one of the home's previous owner, Johnny Bocktune Lew, who had a checkered past.
Lew died several years ago, and the house has since changed hands several times.
