Hiya,
I have a hybrid HS model, so mine doesn't have the panoramic roof, also mine has a few more miles, but has been absolutely faultless, so all I can suggest is look at the service book, there should have been ANNUAL services, in 2012, 2013 and possibly 2014 (or its due one).
Many of the Jazzs have elderly owners so check for panel damage
and enjoy it, when prodded the hybrids go well.
