to start, WELCOME to JCC.
Regarding taking the Jeep to the UK, you may want to research what is/is not legal there and determine if this vehicle will need to be modified to legally operate on their roadways. Are you moving, visiting, military and being transferred? << could be a factor to help you decide if changes are needed/worth cost vs getting different vehicle on arrival.
as far as working on it .. it's a jeep. the same as the ones Jeep sells there, so having a mech look at it wouldn't/shouldn't be an issue -- steering would just be reversed.
Software updates ... might be an issue w the uconnect and gps ...dunno
Good luck in you decision making.........
