Mike Schumacher of Mikes Mobile Repair said, "Your average person is not going to notice a lot of the damage."
Schumacher has seen it all after a couple of decades of working on cars.
Whether it's a bad alternator or water damage, he says water can do serious damage to a car and sometimes that damage can be easily hidden.
"They're going to make them smell nice, they're going to make them look nice, and they're going to wash them all down and make them nice and pretty and it's going to look like nothing ever happened to it," said Schumacher.
The commission suggests buyers look for mud and rust or a mildew smell in the car.
They also say buyers should test drive the vehicle on hills, highways and stop and go conditions, and should always get the vehicle inspected before purchasing.
