Hi,Couple of quick questions ...After a good run in a 2002 Zafira petrol Elegance it is time for a replacement. The car has been pretty reliable other than the usual suspension bits etc (notwithstanding a Monty Python couple of weeks with a clutch/gearbox replacement carried out by a set of drunk monkeys [aka Halfords/AA Autocentre]).Although I have looked at alternative MPVs I am currently looking at a 2010/11 Zafira, most likely a 1.9 diesel, possibly an automatic (wife has arm injury so this might assist).My questions are:1) After reading a number of horror stories about the Zafira diesel (diesel filter failures, overheating, sensor failings etc etc) and an equal number of glowing reports I am a bit baffled ... anyone have any actual knowledge of the diesel's reliability?2) I am also looking at the auto variants ... previous was a manual so don't have any personal knowledge re reliability/usability of the Zafira auto - anyone have any comments? Also is the 'tiptronic' worth a look? I haven't come across this before but it comes up under some 'auto' searches ... I assume (looking at the photo) that it is some sort of semi-auto (clutchless) transmission.3) What is the realistic towing capability of the 1.8 petrol/1.9 diesel? Would likely be small trailer or a motorbike rather than a monster caravan!Appreciateany comments
