I understand your intention, but any loan to a business could be construed as allowing a business to retain jobs. So it's not likely examiners would accept your argument unless you had some convincing evidence that the dealership was about to close down if you didn't provide the loan. Even then, if the LOC was for <=$1MM it would be a small business loan. Also, if the dealership's existence was so tenuous I would worry about safety and soundness issues.
