Task

What to ask before buying this used machine.

Eleven questions for the seller, with what MBB’s records already say about the model next to each one.

  • Built from the model’s records
  • Status per question
  • Copy, print, save

The task

Worked example, then your machine.

It opens filled in with a real example from the reference. Pick your own machine, or use the one you were looking at.

The checklist runs in your browser. With JavaScript off, the listing check has the ten general questions.

How it works

Where the questions come from.

MBB’s published records for the model, and the inspection guide.

  1. Built for the model

    Similar models to rule out, published asking prices by year, the controls and options seen in listings for this model.

  2. Mark as you go

    Asked, answered with evidence, or the seller cannot show it. A question without an answer is a reason to ask more.

  3. Take it with you

    Save the checklist, copy it as text for an email, or print it. Nothing is sent.

Next steps

Carry the machine through.

The machine you pick here is the one the other tools open with.

A checklist, not an inspection or an appraisal. Records describe the model and published listings; the machine in front of you can differ. Evidence standard
