A thought just entered my head --
How does that car look so PERFECT with a showroom shine, when it's not in a showroom? In fact, look at the snow on the ground! Has anyone here driven on public roads up North where it snows? You get sand/salt/grime/slush on your tires, and it gets splashed up on your vehicle.
Long story short, I think 1 or more seminarians had a specific manualia* at some time in the recent past when this photo was taken: wash/wax/buff this vehicle.
* manualia was the term used at the seminary for "manual labor". There were fixed times during the week that the lower years would do 1.5 - 2.5 hours of manual labor, usually in the afternoon. Wood splitting, maintenance, garden, sacristy, grease trap, grounds, garage, etc.
