Don't know how I'll fit another car seat in my little SUV (Jeep Liberty)-

Bride2004

Does anyone have an older Jeep Liberty with more than one carseat in it?  With DS we had his seat (SnugRide then convertible) in the middle because the bulge would stick out between the two front seats.  Now, we have his booster on the passenger side.  We went to BRU the other day and only tried to fit one car seat in my car (Evenflo Symphony) and it was a joke.  We tried putting it in the middle, side and there is no way it would fit.  It doesn't help that DH and I are tall so we can't push the seats up.  I know I'm going to have this problem with most seats.  If you don't have much space in your car, which car seat do you have?  Getting a new car is not an option for us.  Thanks!
