I'm not from the US but I have used kinda similar services before. Two kinds somewhat similar: One is a service where the seller delivers all their cars to a local vehicle inspection service that goes through a checklist and any later faults in a part that was tested is under extended warranty. I'm not much of a fan since who the customer of the vehicle inspection site is can be argued both ways. The other service is where the car gets delivered by the seller to a vehicle inspection site that is owned by a motoring association that the buyer is a member of (like ADAC in Germany for example). This service I have a high amount of trust in since they are "on my side", paid by me and will sometimes take dealers that misbehave to court (sort of like the EFF). A service somewhere in the middle of these two I'm not sure I would trust. If I hire a local mechanic to look at a car for me how do I know he doesn't have a deal with the local seller? If he doesn't spot a fault will he pay to fix it when it breaks? if not, what am I buying? In short: No, I would not use such a service unless it is backed by a trustworthy motoring association that is squarely on my side and who will go to court for or with me if needed.
