The board also approved a motion to allow the department to make a down payment on the purchase during the Friday meeting.
In a previous meeting, the department approached the board requesting permission to purchase the vehicles.
The vehicles -- six Dodge Charger Pursuit cars -- will be purchased from Fletcher Chrysler, Dodge and Jeep, Franklin. They will be purchased at a reduced rate of approximately $22,000 each. According to city officials, Fletcher Chrysler, Dodge and Jeep outbid other dealerships statewide to work with state police departments. In order to receive the state minimum price for the vehicles, departments must go through the specific dealership that has earned the bid.
On Friday, officials with the department said it was in line to receive four 2012 models and two 2013 models.
"Our fleet is down," Police Chief Clint McQueen said. "We needed the (upgrade) drastically."
The department will receive the new vehicles through a loan program through Riddell National Bank. The bank had quoted the department a 2.5 percent interest rate through the loan program.
The loan -- stipulated for three years -- will require the department to pay just under $36,000 per year in addition to the down payment, estimated at a little more than $37,000.
The department had asked the board to approve either a lease or loan program. Riddell National Bank representative Shane Litz was at Friday's meeting and said he had structured the loan similar to the lease program. By using the loan program as opposed to the lease program, Litz said the department could have a savings of just under $7,000.
"I'd like to take advantage (of this)," Brazil Mayor Brian Wyndham said.
Money for the purchase will come from department funds, including monies from the Deferral Fund.
Department officials told the board the money was already in place for the purchase.
Equipment for the new vehicles will be purchased with monies in the department's Traffic Safety Fund and Law Enforcement Fund.
Officials said monies from the Traffic Safety Fund come from statewide "Click It or Ticket" operations. In addition, they said monies from the Law Enforcement Fund come from seizures and fees.
None of the money being used through the purchase is taxpayer money and the money being used cannot be used for other purposes.
Officials said the new vehicles would need to be outfitted with new equipment because some of the equipment from the current vehicles being used is outdated. For example, board members learned Friday the department currently has a 12-year-old vehicle in its fleet with equipment dating back to the 1990s.
The Board meets regularly on the second and fourth Wednesdays of each month. Its next meeting is scheduled for 10 a.m., Wednesday, at Brazil City Hall Council Chambers.
