I did not have a peg perego seat, but I had sold the stroller that went with my seat at a yard sale. So with baby #2, I just took my seat into burlington coat factory and tried it on all the strollers they had on display. I think I ended up getting the same brand of stroller however that the seat was. So you might be unsuccessful in your ventures. I am not sure. I choose burlington, because where I live, the seem to have the most strollers on display and they keep them on the floor not up where you can't reach them to try them out. Best of luck.
