What to ask of a PPI.

Make the inspection answer your questions about the particular car in front of you.

Give the inspection a purpose.

A pre-purchase inspection is most useful when the workshop understands what you are considering, how you plan to use it, and what has already raised questions. Send the listing and available records before the car arrives.

A largely original weekend car, a modified road car and a car returning to regular use may call for different conversations. Explain your plans without asking the inspector to deliver a predetermined verdict.

Choose the person as carefully as the appointment.

Ask about recent experience with the model and the specific version. If the car has been converted or modified, discuss that work explicitly. Confirm any existing relationship the workshop has with the seller or the car, so you understand the context of its opinion.

Agree on the scope in writing. A visual assessment, a road test, a review of service records and additional diagnostic or mechanical tests are distinct tasks. Find out what is included, what needs the seller’s permission and what would cost extra.

Ask specifically about engine testing.

Do not assume a quoted PPI includes compression or leak-down testing. These may be separately priced and require additional time, access and the seller’s authorization. Ask the workshop whether one or both would be useful for this car, and request results for each cylinder if testing is carried out.

Read our guide to compression and leak-down testing.

Ask for findings you can act on.

A helpful report explains what was observed, how it was checked and what could not be assessed. Photographs can make the explanation clearer. Where work is recommended, ask the workshop to separate immediate concerns from future maintenance and cosmetic preferences.

Request estimates with a stated scope. Some costs cannot be established until a component is examined more closely. Keep those uncertainties visible rather than folding them into an apparently precise total.

The useful result is a clearer understanding of the car, including the questions the inspection could not answer.

Bring this to the appointment.

  • Send the seller’s description, VIN or chassis number and available history in advance.
  • Confirm the workshop knows the model and the specific transmission configuration.
  • Agree on access, road testing, diagnostic work and any additional tests before the appointment.
  • Ask for a written report with photographs and an explanation of limitations.
  • Request a distinction between immediate concerns, likely near-term work and cosmetic preferences.
  • Ask for separate estimates where work is recommended; establish what each estimate includes.
  • Review unresolved questions with the inspector before deciding on the car.

Use the checkboxes as a reading aid. Your selections are not submitted or saved.

Keep the report in the car’s story.

An inspection describes a car at a particular time, within an agreed scope. Preserve the report and any subsequent repair invoices together. That sequence helps future owners understand how the findings were addressed.

The Analog Stable’s planned specialist network is based on relationships, with no workshop referral fees. Buyers will choose and engage their own inspector. We are still developing that network and are not currently offering inspection bookings.
