My D4 has done 15,000kms on a set of Cooper AT3's. When I went in to get the wheels rotated and an alignment check at 10,000km the guys said I did not need to have the alignment done.
When the car gets serviced (every 6 months) they do not do the alignment. It is not a dealer, but a Land Rover Specialist. So maybe you are being taken for a ride.
