The officers opened the boot and discovered the number plate KCX 385D. Assorted documents of a cosmetic company were also found in the boot.
Police believe the two were killed elsewhere and bodied dumped at the scene.
Ruiru head of Directorate of Criminal Investigation Justus Ombati said they are investigating the murder. He said they are yet to identify the slain men.
“This is murder, which happened elsewhere and bodies dumped there in the car. We are pursuing the issue,” he said.
He added that they are yet to know the motive of the murder.
Ombati said the bodies were moved to the City Mortuary, where they plan to conduct an autopsy to identify them and establish how they died.
He added preliminary findings show the men were shot at close range.
He added they will conduct ballistic tests on the recovered cartridges to establish the kind of gun used in the shooting and that the fingerprints picked from the bodies will show if the victims had a history of crime.
The car was towed to the local police station.
The discovery of bodies has been on the rise in the country amid calls to solve the trend.
Most of the incidents are still under probe. Up to 70 cases are still being investigated.
