my first suggestion would be to consider an x with the 8spd box, the X1 came with the 8spd from 2012 in the facelift and the X3 was 2014 IIRC.
based on mileage you would want to look at the following;
control arms
dampner pulley
tyres
service history in relation to mileage -
gearbox oil service
diff oil service
