Hi,
Are you still looking for a quinny stroller?
I have a quinny zapp stroller with black seat, zapp xtra seat in rebel red and a maxi cosi in red.
I only used the quinny zapp frame with the maxi cosi so far as my daughter is less than 6 mths old. But I have opened up the seat that comes with the original quinny zapp and the zapp xtra seat to test to ensure that it is in working condition.
Do PM me if you are keen to view the pictures. If possible, I am hoping to sell it as a complete set.
