Harper has been using two armoured cars with Ontario plates while in India -- something he has only done in Afghanistan and Haiti before.
He arrived at the president's official residence today for an official welcoming ceremony in one of the vehicles - a Ford SUV.
A Canadian official explained Monday that he had been offered the use of a vintage-looking Hindustan Motors Ambassador car.
But an Indian bureaucrat with the Ministry of External Affairs told The Canadian Press on condition of anonymity that Harper had been offered an armoured Mercedes for his entire visit -- with the exception of a stop in Bangalore where it was the state government taking care of his car.
The official also noted that the Indian Prime Minister Manmohan Singh sometimes brings his own vehicles abroad too.
The RCMP, which is in charge of Harper's security arrangements, would only say it makes its decisions after evaluating current events and locations.
There was no immediate information about how the vehicles were transported to India and at what cost.<
