new zafira

hi,
i`m not sure if this is the correct place to post but here goes.
i`m looking at buying a new zafira 1.6 exclusiv on the scrappage scheme, but reading reviews there seems to be a lot of problems with clutches breaking and spare wheels being stolen(an option i am looking at, the spare wheel that is)and various other problems especially with the diesel models. i just like to hear it from the horses mouth so to speak, if any of you have experienced any problems and what i should look out for. another thing is the a frame creating a blind spotand has it created any problems or does it make you more aware at junctions and the like. i have had a test drive of about 10 mins and i liked the drive, maybe i should try for a longer test drive. another thing has come to mind is what is the comfort like as we drive to my sister in laws a few times a year which is a 500 mile round trip, there is a comfort option on the seats. thats it for now hope you can help.
thanks.
