What €24 buys, put next to what it saves

Cracks in the floor above the rear subframe mounts are two or three days of reinforcement work, and so is rust in the rear arches, as bodywork. The complete cooling job is a day. Everything else on the list is half a day or less. The guide is €24. It will not stop any of that from being needed — but it does tell you which of them you are looking at before you agree a price, and that is the whole of the difference between paying for a car and paying for someone else's postponed maintenance.

The six questions that decide whether this car is a good buy

  1. Has anyone looked at the floor above the rear subframe mounts?
  2. Has the cooling system been done as a complete job, or piece by piece?
  3. Is the engine dry?
  4. Is there a loud noise from the engine bay?
  5. What do the rear arches look like from underneath?
  6. What is the mileage, and does it come with a folder?

Questions

What exactly do I get?

The full guide as a PDF, 17 pages in A4, plus a phone edition to read at the car; and the inspection card, 3 pages to print and take to the viewing. €24, VAT included.

How is it delivered?

Straight after payment you get a download link for the guide, the phone edition and the card. No subscription, no account.

Can I get a refund?

EU consumer law gives you fourteen days to change your mind. For digital content that right ends the moment delivery starts, provided you agreed to that at the checkout. If the file will not open, or you were sent the wrong car, write to us and we will fix it or refund it.

Who handles the payment?

Lemon Squeezy, who sell the guide to you as merchant of record. They charge the VAT at the rate of your country, send the invoice, and email you the download link. We never see your card.

Why are there no prices in it?

Because a price we cannot verify is worse than no price, and because a price would be wrong for most of the people reading it: workshop rates across Europe differ by a factor of two or three. What does not change is how much work a job is, so every point says whether it is an hour, half a day, a day, or a week in the workshop. Ask your own workshop for its hourly rate, and every hour in the guide becomes your own number.

Is this advice about a specific car?

No. A guide tells you what to look at; it is general information about the model and not advice about a specific car. Have every car inspected before you buy by someone who knows the engine.
