I'd guess they cost substantially more since car parts can be much less tolerant of humid air and thus use less expensive materials. Stainless steel is a LOT more expensive.
When we first bought Persephone (about 8-ish years ago) I got so annoyed with an apparently backwards one-way valve on the fresh water tank fill hose that I replaced it with a straight-through fitting and used cheap automotive hose clamps. A recent check showed it to be very rusty. It was only after I installed it that I learned about using SS fittings on a boat, even on Lake Michigan (fresh water, not salt water). I will replace it soon when we fix up the rest of the plumbing... ... though first we need to make sure we won't sink due to the failing stuffing box! (I posted about that recently; we've decided it may be failing because of some wobble at low RPM's that smooths out at typical cruising speeds. That could be due to engine mounts. We're going to locate and hire a mechanic to survey the situation.)
