2nd baby - which Quinny model are you interested in? I was deciding between Bugaboo and Quinny Buzz back then and got a Bugaboo instead. I got it from Habour front Mothercare and the guy there is great who showed me a full demo of both strollers.
Here are my thoughts:
I felt that Quinny Buzz is too bulky when folded and its very heavy for me to handle if i go out alone with baby. (13kg if i am not wrong?) Bugaboo is only 6kg. Also, its not easy to push around in MRT as its quite big. There is also very minimum storage space for baby stuff. Although they have a small bag provided, but its definitely not enough for me. I think Quinny Buzz is a good buy if you drive (provided you are driving an SUV - large storage space needed) as you can directly detach the seat to serve as a car seat. It is also easy to keep, but you definitely need both hands. If you are looking for strollers which can be opened and closed with one hand, go for Japanese brands like Combi and Aprica. Manuveure wise, the wheels are great and i like the stablility of the Quinny. Oh by the way, Quinny Buzz offers full recline position so its a plus point for this stroller. Not sure about Pre perego??
Hope this helps.
