If you are a serious buyer and the seller won't let you drive the car, then there are bigger issues at hand. Show up with cash, tell them if they won't let you drive it then you're gone. If the car isn't even drivable then a PPI probably isn't that important anyway, just assume the worst and bid accordingly. I've had eight Porsches and only had a PPI done on one of them, after you get past the mystique you realize that they are just a car.
