We own a Scion TC, and have a BABY...?

I currently own a Scion TC. The back seats are roomy but not when there is a car seat involved. With Aubree's Graco Snugride car seat behind the pengers side, it makes it nearly impossible for an adult to ride comfortably in the front. Are we going to have the same problem (or worse) when she is moved to the convertible car seat?
