But police, who are on the lookout for possible car bombs after a spate of terror attacks in France over the past year and a half that left more than 200 dead, called in bomb disposal experts when they spotted the suspicious vehicle.
In September, police found a car with its hazard lights flashing near Notre Dame cathedral which contained gas canisters and which they believed was intended for use in a terror attack.
When the bomb disposal experts arrived at the black Porsche late morning last Friday, they were taking no chances.
They attached a small amount of explosives to its bonnet and blew it open before ascertaining that there was no bomb in the vehicle.
Olivier arrived at the scene a short time later and was astounded - and furious - to find his sports car badly damaged.
"They (police) contacted the leasing agency I bought the car with, then called me, and I explained the situation," he told Le Parisien, admitting that he shouldn't have parked at a taxi rank.
"I apologised and said I would go there immediately. But obviously they didn't take this into account, because the bonnet was already blown up by the time I arrived," he said, adding that he was considering legal action against the police.
