Most of what the Capital One Quicksilver reaches in car-rental status takes a multi-step match; the first step doesn't. Enroll the card's Benefits tab and 
Hertz Five Star status lands on your account complimentary — for US cardholders. Every other status below builds from that one enrollment.
From Five Star, one route picks up 
Sixt Platinum — status that doesn't expire — on its way to 
Avis President's Club. A separate route also starts at Five Star, picks up Avis Preferred Plus and then Hertz President's Circle before finishing at 
Enterprise Plus Platinum; crossing between rival brands like this is normal for these matches. The reference below maps every hop of both chains.
The Five Star status is the easy win — you get it just by enrolling the card's Benefits tab. The two longer chains only pay off if you specifically want Avis President's Club or Enterprise Plus Platinum; for general elite car-rental treatment, Five Star alone already delivers it.
