Good luck, i bought a 42k mile Zafira B 2.2, 2 months ago. I never noticed the timing chain on the test drive, and tbh it drove fine all the time, but a few days of ownership and i heard the rattle. The car has a full dealer service history, at all the correct intervals, no expense spared, yet it needed new balance kit, and new timing chain kit @ 42k?!?! Luckily i was covered under consumer goods act, as the warranty company were not interested at all, and the dealer picked up the whole bill.
