Your Mercedes diesel van is having issues and you need to take it to a shop.

You call around to a few places.

Who are you more likely to trust?

A Mercedes diesel mechanic who recognizes it as a common problem and explains exactly what’s wrong and how to fix it.

Or…

A generalist mechanic who says, ‘It’ll cost $149 for us to take a look.’

Pretty easy answer 😀

It’s usually better to go narrow and deep than wide and shallow.
