Eli5 How come auto repair garages don’t keep spare car parts on site and have to order them?

671 views

I’d understand them not keeping spares of larger parts at the garages due to space issues, but I’m confused they wouldn’t have something like spare O-rings around (one is stopping my car from getting fixed/tested and the garage told me there’s been a shipping delay).

There are parts that most garages will keep stock of, like serpentine belts. Those are generalized enough across manufacturers that it’s sensible to keep a few in stock.

That’s often not the case with more specialized parts especially critical ones like o-rings. A BMW o-ring might be different from a Subaru o-ring, and it’s easier to just order the part when needed than try to build an inventory that you may or may not use.
