Stroller bable

What is up with the Bugaboo? For those who have no idea what a Bugaboo is, it is the baby stroller of the moment. It can be seen all over Rome, and all the hip and happening parents seem to have it. I was very close to purchasing it, when my very wise husband convinced me that the Inglesina was the way to go. I have to say, no regrets there! Firstly, the Bugaboo is way too bulky and big to fit into most elevators, and is a lot heavier too. I already hate folding up the Inglesina since it is easy, but not the easiest of things to fit into my little car. I would have to leave the house half an hour earlier to deal with the Bugaboo, I imagine.
Moving on, I am now looking for the appropriate car seat for baby since he is outgrowing the one we have. This is not easy. My car is not Isofix friendly, so must find something that can be used with seatbelts and Isofix for when we eventually get a new car.
Any advise on car seats? Please feel free to share.
