A Pre-purchase inspection can range from a quick walk around to check for obvious body damage, to a full day invasive interegation of every working component on the vehicle & extensive test drive. These parameters should be pre discussed. If I were ever in need of this service I would insist the 1st step would be to remove & inspect the oil filter, & this would conclude the PPI if it did not pass the 1st step. Cost should be commensurate with time spent to accomplish the buyers objective.
