I'm not defending it, just explaining it. Different dealerships will have different tolerances for risk, including allowing employees to bypass standardized requirements. I'm not making anything up, just explaining what's most likely going on with this particular dealership, and how it's not unusual.

If your dealership is letting you drive off with a vehicle with a personal check (not even a cashier's) and without any kind of credit check or database identity verification, that's actually pretty wild. I assume you know the owner or salesperson personally. Otherwise, you could be a rando passing them a forged check, and then they'll be out both cash and car. I don't know many businesses willing to take that $10K+ risk.
