Let’s be clear — many (if not most) people buy cars without getting pre-purchase inspections, and many (if not most) of those people don’t think twice about it or regret their decisions later on. Whether you get a PPI largely depends on your situation and your risk tolerance.
So, even a risk-averse buyer might be fine skipping a pre-purchase inspection on a relatively new vehicle with a reputation for quality if they know the owner well and have seen the service records. That said, we’ve never heard of someone regretting their PPI.
