The Roundabout has the same bottom slot measurement as the Marathon -- the Marathon just has a taller shell with an extra top slot to allow bigger kids to stay harnessed longer....

I'd like to add that Subaru buckles are known for being very long: you can rotate the short end up to three full 360 twists or you can buy a seatbelt extender.

Also, I'd like to address the issue in the database about the base not being flush with the vehicle seat cushion. So long as less than 20% of the base hangs over the edge of the cushion & it moves less than 1" at the belt path (with the required 45 degree angle for newborns) then it's a safe install.

A LATCH Compatible Convertible Child Seat, the Britax Marathon can be used rear facing 5 to 33 pounds and forward facing from 20 to 65 pounds.
