Saying hello

Just joined. Owned a Mk2 Zetec petrol which I loved, but age slowed it's towing ability so have just bought a Mk3 2007 registered Zetec 2.0TDCi only 22000 miles. Very impressed! Added bulbs to footwell and looking for other subtle upgrades. Have to add reversing sensors after my Tow Hitch fit next week. What other mods do you just have to add bits to to make them work? Can't believe Ford would not add two 90pence bulbs.
