Hi!
I have a Graco travel system, and it's great, but make sure that the stroller part will fit in your trunk! We didn't test it before we purchased the set, and the stroller fits (we have a honda accord, with an average sized trunk, so we didn't foresee any problems) but it's a battle every time.
Other than that, the stroller has lots of storage, and my favorite... cup holders
One more piece of advice, if you're looking for a car seat/stroller combo, go with the one that allows for the most weight. I think that most go up to 22lbs, some will go up to 30lbs... The 30lbs might buy you a few more months before you need to get another seat.
Good luck!
