I saw this in my neighborhood today. Left front wheel has five bolts with a different hubcap. The other three look like the left rear, not sure how many bolts. I thought all Fits were 4 X 100.

 

That's an aftermarket plastic hubcap from the parts store.

I bought similar ones when I got my winter-tire steel rims. It occurred to me later I should have gotten the "five lug" versions instead. Free upgrade don't you know.

 

Yes, but how does it work with five bolts vs. four?

 

The five "bolts" are plastic and purely cosmetic as part of the hubcap. The steel wheel underneath is almost certainly the expected 4x100.
Someone was lazy and bought the first or cheapest hubcap they could find.

 

Exactly. Those are just five chrome plastic nubs that look like lugnuts.

 

Ah, thanks. Well, I like the look of that one better, but the owner didn't replace the other 3.

 

The owner somehow lost one hub cap and when he went to replace it he found it no longer available, or just too expensive so he settled for .... pretty much anything which somewhat looked the same.
