Fi,
Just get it serviced by a good, reliable mechanic. Change all the lubes and filters (even the funny one by the fuel tank if it is fitted!), replace leaking seals, cam belt and anything iffy. Check shocks/springs and bushes, body mounts and the rear floor. Throw in some new bulbs in the head lights. Pack a SMALL spares pack for self fix and get recovery for as much of Europe as possible.
Fill up at a BP station on the way to the ferry and splash out on some Ultimate diesel for the first tank.
Oh and don't worry
I can't remember wher you live but if you are stuck for a good garage, drop it down here and we'll do it at work. If you live over Kent way get D90SV to do it as he runs a reasonable service bay...
