He was told of the proposal by the Permanent Secretary of the State House, Mr. Nebolisa Emodi at a briefing on Wednesday.
Directing that the proposal to procure the cars be dropped, President Buhari said that there was no need for them since the ones he inherited from President Jonathan were good enough for him.
He said: "I don't need any new cars. The ones I'm using now are just fine," a source at the briefing quoted the President as saying.
He however welcomed other initiatives presented by the Permanent Secretary to reduce the operating costs of the State House and strengthen its Finance and Accounts Internal Control Mechanisms.
The President stressed on the need to capture all State House expenses within the approved national budget in order to avoid the frequent recourse by past administrations to "Presidential intervention funds".
The Senior Special Assistant to the President (Media & Publicity), Mallam Garba Shehu confirmed that in keeping with his commitment to prudence in the management of national resources, President Buhari will continue to use the cars left behind by President Jonathan and has withheld approval for their replacement.
State House sources told our reporter that the proposal to procure the new cars was first made to President Jonathan before he left office.
The former President directed, however, that it be represented to President Buhari for approval on his assumption of office since the cars could only be delivered some months after the May 29th, 2015 handover date.
