IMHO, a chance to remove some of the "noise" if resources permit.

Suggestion: Add a field for the last entry date, and remove all entries over 90 days or so without an update that have less than a meaningfull number of tanks (say 10 or so, at least). This will remove the fast-starters that don't stick with a program and leave first tank distortions, newbie claims, etc. in the data.

Perhaps change the screen print color for cars that are inactive. (Over the minimum tanks, but no update in the 90 day or so time period.

It is the ignorant among us that will eventually destroy us all.
