I have been thinking to go ahead and purchase a convertible car seat since there's some pretty good deals right now on Amazon. We are currently using a Chicco Keyfit for our 6 month old. I have been looking at the Diono Radian RXT, Recaro Proride, and Britax Boulevard 70-G3. Honestly the more I look the more confused I get. We drive a VW Jetta and a Honda CRV both older models without latch and would prefer to be able to keep him rear-facing as long as possible ideally in the center seat.

The Diono seems awesome but I'm concerned about how it would fit in the Jetta. The reviews for the other two seem to point out a lack of leg room while rear-facing.

Any advice on these three models or another recommendation all together?
