Task

Compare two machines.

Differences, the source behind each one, and the questions to settle with the sellers.

  • Differences only
  • Sources on every row
  • Questions to verify
01

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 comparison runs in your browser. With JavaScript off, open the two reference pages of the worked example:

Haas VF-2 · Haas VF-2SS

How it works

What the comparison shows.

The same evidence rules as the compare tool, set up for one decision.

  1. Differences only

    Rows where the two machines agree are hidden, so what is left is what you are choosing between.

  2. A source for every row

    Specifications come from the reference page for each model, asking prices from MBB’s published records. Missing evidence is shown as missing, not as a pass.

  3. Questions to verify

    Each machine’s open questions become a list to put to the sellers before you compare offers.

  4. Saved in this browser

    Save the comparison to My research, or copy its link. Nothing is sent.

03

Next steps

Carry the machine through.

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

Specifications describe the model as published; a specific machine’s year, control and options can differ. Asking prices are what sellers asked, not completed sales or appraisals. Evidence standard
