I think main benefit of going to a mechanic is the multipoint inspection. If you’re not good with cars, you need someone to find out if something needs to be fixed before the car breaks down on you.

More likely to get told a pack of lies and to end up fixing things that don’t need fixin’. And yah yah I know I know “your mechanic is trustworthy”. Funny how everyone says that but I’ve only met a few honest mechanics in my long life. And yes I know how to tell an honest mechanic from a dishonest one. Been hard-core wrenching for more decades than most here have been alive.
So what’s the solution? Become a mechanic?
