Wasting money on government vehicles is something the Department of Defense does well, according to a new inspector general's report.

The IG report said the Navy, Defense Logistics Agency, Pentagon Force Protection Agency and Washington Headquarters Services are costing taxpayers unnecessarily through poor management of 774 "nontactical vehicles," at a cost of $2 million.

Among the problems were failure to conduct annual reviews or keep daily usage logs. Maintenance was not a priority. Official vehicles — sedans, light trucks, heavy trucks or buses — that are driven half as much as the annual average are officially considered excess and thus a waste of tax dollars, according to the IG.

A 2010 Chevrolet CG3300 passenger van, leased for $3,168 annually, was driven only 583 miles, according to the report. A Ford truck cost almost $4,700 annually to lease and was driven only 37 miles.

The IG's office concluded that the four agencies could save DoD $7.2 million in lease costs over the next six years through better management and getting rid of the extra vehicles.
