What to ask when you call
Will the car go on a lift with the wheels off?
If not, the inspection is not a PPI.
Do you use PIWIS or Durametric?
Factory-level diagnostics are the only way to read over-rev ranges and stored DME data.
Do I get the written report directly?
Not the seller, not a phone summary. You.
The full list, including generation-specific items, is in the PPI guide.
