Would you let a random stranger plug "diagnostic" gear into your car? I certainly wouldn't.

would you let them touch your car ? Or even drive it? YOu want to sell a car to a dealer. they will inspect it .If i want to buy a car I will inspect it to the best way possible .This means MOT history and reading codes after a test drive to make sure they have also not cleared any !
