Hi guys so I am faced with the exact problem that is in the title. I want to pull the trigger and buy a rebuilt title F80 that needs a little bit of work to get running again, but, I am think the seller got the car, took the good motor and swapped it out for a blown motor. I have the VIN of the car and the VIN of the engine that is currently in the car. Is there any way to check to see that they match? Any help would be much appreciated. Thank you!
