2. VEHICLE AND AIRCRAFT MANAGEMENT 2.1 The effective disposal of obsolete vehicles is a cause of concern. The depot used to house these vehicles was not fully secured and increased the risk of theft. Long delays and backlogs in the auction procedures of vehicles are also a cause for concern. The Committee was also informed that the registration of vehicles on the eNaTis system (electronic national administration traffic information system) is too costly, at approximately R500 per vehicle. Revenue generated from the auction of vehicles had to be relinquished to National Treasury, and was thus lost to the base as an additional revenue source.
