It was a straightforward question; your childish rant is wholly uncalled for TT, but I hope you got something out of it anyway.
It may well have been a straightforward question that you posted, but my reply certainly was not a childish rant. Nobody else, appart from your good self seems to have taken an issue with my stance. Shall we just agree to disagree on that issue, and call a truce?

The answer seems to be that it doesn't actually detect all illegal movement at all.
Oh, all the Tracker units detect "illegal movement", but some units only detect
certain types of illegal movement (moved without the keys), whereas the more expensive/comprehensive units detect additional methods of illegal movement (including movement with the keys).
The website is incredibly unclear (to the point of being misleading) on this point,
I sort of agree with you, but maybe Tracker themselves wish to be slightly cautious on the info they offer. However, if you phone them directly, rather than, say trying to get the info from your VW stealer, they are much more helpful (usually!!!!).
presumably as it highlights a shortcoming in the lesser systems, in that if your keys are gone the system does nothing until you notice the car is gone.
Well, you are right to a point! But not every car which is stolen, is taken with the keys, and in that respect, the "lesser" Tracker systems are still very, very good, with a proven track record. Sadly, the crims are now aware that to steal the keys before the car itself, means it is so much easer to take your P&J. However, one thing to bear in mind when choosing which type of Tracker would have to be the type of car you own: is it highly desireable in terms of its' potential for resale, or merely just because it is a fast car with less value for resale!
Living near to one of Europe's major docks, this would be a concern. Unlikely they could be quick enough, but still a concern.
Now that would be one very important issue to weigh up when considering which unit to fit. Bear in mind though, that all the major ports and docks have the Tracker detectors on them!

I think itÂ’ll have to be the premium system then.
Wise move!
