Something to consider is where you live. I currently live in a single-family home neighborhood on the city's south side, with an attached garage. However, I used to live in a condo in a high rise downtown (multi-car garage parking) and then before that in a third floor apartment in a walk-up building (street parking). I used a Graco travel system with my child, but there is no way on earth I would have lugged that heavy beast of a thing around downtown or at the apartment!
My Graco was simple to use, easy to fold with one hand, but heavy. Fortunately I drive a larger sedan with plenty of trunk space but even then the travel system ate up a bunch of it.
Go to Babies R Us and ask them if you can pull your car up to the curb and practice putting the stroller away in your trunk. You should also be able to take each and every model off the shelf and try to fold it. My rule of thumb when selecting a model was, if I couldn't figure out how to fold it on my own and within a few minutes, it got crossed off the list!
