It'd be a pain at the multi-dealership-network level, sure.
But an individual dealership has what, 50 cars in stock? That seems easily manageable to me. I'm old enough that I've seen far larger operations running on paper.
Of course, the days of paper-based paperwork did require businesses to employ diligent and numerate clerks, and to have filing cabinets, manual calculators, photocopiers, whiteout, and suchlike. I suppose they could have run into some challenges around that sort of thing.
That would be a very small dealership around here, even in the suburbs. 50 cars on the lot was the amount I was seeing during the height of the pandemic supply chain problems and I was amazed at how empty the lots looked.
Yeah, I assume they had an assortment of clerks who’d be hard to replace right this moment, especially given that the duration of their employment would be like, what, a week or two? However long it’ll take to get this attack taken care of.
