Abstract: The assessment of funds related to motor vehicles includes: receiving a vehicle identification for a motor vehicle from an identification system at a fuel station as part of a fueling transaction; obtaining vehicle information and a funds calculation method from a vehicle assessment database using the vehicle identification, where the funds calculation method comprises variables for the vehicle information; calculating funds to be collected during the fueling transaction using the vehicle information according to the funds calculation method; and determining a total cost of the fueling transaction, the total cost comprising the funds to be collected. Other types of funds or non-fund related functions may be taken into account, such as driver socio-economic data, insurance status data, license status data, fees and fines data, law enforcement data, and data collection for research, analysis, and planning, thus providing a tool for customizing the assessment of funds related to motor vehicles.
