I find this a good feature.. i was in town a few months ago and someone tried getting in my car while i was in it! The locking system stopped them!
However annoying it is if you have a valuable car then i suggest keeping that feature.. you never know when you'll need it.
I think Paul Norkep's brother in law or brother had his car hijacked and the driver was put in hospital? (paul please let us know how he got on?)
An Aristo Vertex would be on a hot list!!! If i was into stolen cars then i would choose a vertex as one on my list! But i dont steal cars :P
