NIA had arrested Inspector of the Mumbai Police Crime Branch, Sunil Mane for his involvement in the case.
Mane is the third police officer to be arrested in the case, after Vaze and the latter's Crime Branch colleague Riyaz Kazi.
The NIA is trying to ascertain whether the car is in any way linked with the Vaze case or the death of Thane businessman Mansukh Hiren.
The convict, who has links with Mumbai's underworld, has been undergoing treatment in a Delhi hospital since the last few days.
NIA, which is probing the case, has also found that Waze along with his driver parked the SUV near Ambani's house, the sources said.
The arrested Assistant Police Inspector Sachin Waze, whose name came up in Mansukh Hiran's death case allegedly used a fake Aadhar card while booking a room in a 5-star hotel in Mumbai.
The Volvo car with the Maharashtra registration number was seized on Monday, an official said, adding there is no clarity so far on who owned this car.
The scene was recreated late on Friday night, in which Waze was asked to walk there for some time wearing a white kurta, he said.
The Anti-Terrorism Squad, which is probing Hiran's suspicious death, has recovered CCTV footage of a spot near Chhhatrapti Shivaji Maharaj Terminus (CSMT) in south Mumbai.
The editorial also praised the former Mumbai Police Commissioner Param Bir Singh and alleged there was a certain lobby in Delhi that had grudges against him.
A team of the National Investigation Agency (NIA) conducted the searches at Waze's place in Saket area of neighbouring Thane city in the afternoon, an official said on Wednesday.
Vaze was sent to NIA custody till March 25, on Sunday. He had on Saturday moved an anticipatory bail application at Thane District and Sessions Court.
Sudharma Waze also alleged that his brother Sachin is being implicated in the case.
Waze had on Saturday moved an anticipatory bail application at Thane District and Sessions Court.
