Who actually goes to the garage?

No, but seriously. The topic is too broad. A suggestion would be to create individual topics for the inspections (1st Inspection, 2nd Inspection). What needs to be done (should be done), what is the technical background, and where can it be checked. Frequently asked questions are, for example, Longlife, timing belt, oil, etc. This would help beginners (and that's who we should be addressing) much more than specific problem solutions. If they wish, there is also plenty of further information available here.
