The young couple, who did not want to be named, said there was a child in the van parked on the verge minutes before the Commodore crashed on August 18.
�Our first reaction was that we hoped no one was hurt,� they said.
�Luckily there was no one in the van at the time.
The couple�s neighbour, a mother-of-three who did not want to be named, said she heard a bang as the car slammed into the van.
�I heard the car speeding and squealing before a big bang,� she said.
�I�m really happy and relieved no one was heart but my sister-in-law�s van is a write-off.�
The couple, who have lived in the house for three years, said they were also worried their house would collapse as the Commodore was removed from their garage.
�Thankfully the State Emergency Service was incredible and managed to remove the car and support the garage with a metal structure,� they said.
�It�s just a big inconvenience and is going to take weeks to fix, estimated to cost $20,000-30,000.�
A police spokeswoman said the crash happened about 10.30am after the driver of the stolen white Holden Commodore drove along Walderton Avenue before losing control, hitting the van and garage of the house.
The spokeswoman said witnesses saw a dark-skinned man wearing dark-coloured clothing leaving the scene in a dark-coloured car, believed to be a Holden Commodore.
The white Holden Commodore had been stolen during a burglary at a Hilton Place home in Duncraig earlier in the morning.
