I'm looking at buying a mk4 mondeo as a family car, only really looking at the titanium models but can anyone tell me what the difference is between a normal titanium and a titanium x?

With the budget i want to spend it will probably be a pre facelift 2008/9 model.

I went to look at a 2008 2.2 tit x over the weekend which was a lovely car, the only thing that worries me is buying a modern diesel of that age and the expensive issues they can give? I think I've almost convinced myself to take the risk!

What you all think?
