2013-14 mondeo wagon: what to look out for?

[cooperplace]

When the magna wagon eventually dies, the choice for its replacement seems to be narrowing down to a later MC diesel wagon. I'll look for a low kms FSH car. There's a few areas where I'd appreciate advice:
1. Is it worth paying more for the higher trim levels?
2. do these go LX>Zetec>Titanium?
3. What should i look out for in a test drive, apart from the obvious? I'll especially check the trans shifts OK.
4. What are the headlights like, especially low beam?
5. Anything else?
Thank you!
