That's what I've always understood. The 1.1 was non interference and the VVT was/is without exception, interference however, I'm not entirely sure if the last of the 1.2 60hp (so up until the 68 hp VVT engine took over in 2011) were interference or not. However, experiencing a broken cam belt when away from home would be a most unpleasant and inconvenient thing to have to endure, so I will never exceed the recommended change interval. having said that they don't seem to be too hard on their belts as there are a number of posts on here from folk who have run them well past the recommended interval without any drama. I think keeping an ear out for water pump/idler bearing failure is probably more important.In Panda's they were non interference up until 2010 as far as I'm aware with the introduction of variable valve timing which is when the 1.1 was discontinued which never received VVT, in 500's they have been an interference from day one in 2007 as the 500 was the first FIRE engine to have variable valve timing.
Edit. When looking at 1.2 engine versions, don't assume that because it's a 169 model that it'll be non interference. The last of the 196's used the VVT 69hp engine which can be easily identified by looking for the VVT valve on the cam cover just to the right of the oil filler cap.
