It's a donated vehicle. They don't have time or resources to fix these things. They just sell them as fast as possible and give the money to charity. I volunteered at a place like this. 99% of the cars that come in just get hauled to the scrap yard. Occasionally we would tear some parts off first to sell. If a vehicle came in and actually ran and drove we didn't touch it, it just went in autotrader asap as is.
Still looks like they would send a detailer out there in leu of them getting dirty. There are tons of "porta-detailers" around these days for some good prices, and if one of them has any intelligence they'd see this could be a great contract
The charity, on the other hand would reap a much better value from their supporter's donation, who in turn would receive a better tax write off.
It would still make more sense to me, no matter how ya slice it
