Used car dealership reconditioning

I’m considering buying a used car and would pay for a 3rd party ppi. When I asked the sales guy if anything had been fixed/repaired during the reconditioning process, he said no, that the car came in very “clean” and was in really good condition. The car is a 2015, so I find it hard to believe that the dealership didn’t find anything that needed replacing/fixing, even if it were something simple like brake pads, shocks/struts, spark plugs, filters, etc.

Does this sound strange? Is it common for dealerships that claim to do reconditioning to not make any repairs at all before selling a car?
