i do this if i take my car to an area thats a bit dodgy, just means it'll take em that much longer to get the car started. if they realy want it though, they will take it. if you have enough time you can bypass immob as well, if you know how.
will stop your average car theif for a bit, if they had a bit of dub knowlege tho they would know how to jump the pump relay socket to get car started. the mk3 has an advantage here in that the fusebox is a right slag to get to compared to a mk2 though
