Always get a PPI on any used car. I see posts every day in this subreddit, “Should I by X Y Porsche with Z miles? Is this a good buy?” We don’t know. we don’t know the history of the car and we are not able to mechanically inspect the vehicle. Only a mechanic can tell you what needs to be spent.

Buy a pre purchase inspection every time and use it as a negotiation tool. The exception is CPO. CPO = Warranty + Inspection.
