Brake fluid reservoirs: $30 vs $80

[David]

Anybody see the difference between these two brake fluid reservoirs other than the price ?

Second one is for an automatic, doesn't have clutch port. And that seller prices above retail as he probably buys from BMW.

And it is not clear if either has the fancy cap with the built-in float + switch that signals when your fluid level is low. Those caps tend to be costly, so my guess is that these two reservoirs come with plain caps.

Good catch(es).
Noob question: What's a Clutch Port ?

I was hoping to get a nice new one to match the new window washer tank I bought. Hopefully I can use the fancy top on my current unit.

I'm actually running out of things to buy for this car....8 years later.

Clutch port-it feeds brake fluid to the clutch cylinder via a hose that connects to it off of the side of the reservoir.

You can, yes. The diameter and threads are the same between plain caps, and the ones with the float & switch.
