Corporate means it was used as a transport for the needs of the company. This doesn't mean that the car is bad. Sometimes it is even more profitable to buy a corporate vehicle from a company than from a private person. Because global companies monitor the car with special attention, this car brings income and money to the enterprise. They often hire a personal driver who is qualified in this field and drives carefully. But how the private owner drove, you will never know. Maybe he went too fast and burned the gearbox or chassis and wants to get rid of this car.
