Tracker not compulsory out here and if it does get stolen and ends up in the north of the island that is it! there is no formal recognition of the north by anyone or any country and so the insurance company cannot pursue it, people have been shot for lowering the flag of the 'other side' and the shooter caught on camera and they still cannot get hold of the killer! so getting back an x5 no chance,Politics.
Anyway if you are going for the petrol there should be no lurch issue eh?like I said twice in a year for me and no idea if it damages the transmission a tad worring but I am going to try and enjoy having the car instead of worrying, and people do envy it alas, got keyed at the garage after I was in a small accident, couldn't make any sort of claim as didn't have photos of all the panles before taken it to the garage! and the damage assessor who checked the car didn't take pics of the whole car , just the damaged part before and after so i didnt have a leg to stand on! so I have had my share of nightmare with the x5...diesel 28-30mpg is a plus though, or just get a toyota rav, one of the old ones that last forever and upgrade the interior
