Other admins complained of several errors, so I can't just rename without confirmation from other people.
e.g. for cases like this: https://imcdb.org/vehicle_2054983-Chevrolet-1956.html
Bel Air is the most well known name, but not especially the most common... it was just a trim name (maybe it is right, but I have doubts)

And this one was already posted before:
https://www.imcdb.org/vehicle_121996.html
but the answer was not on the page until I ask for it. Why post it here?

This is why I know nothing, I probably don't like seeing forever unknown vehicles on the site
