I've got total closure on mine. it's great. if you don't want them to close just turn the ignition on and off quickly and it'll chirp. then arm away. if someone leans in it'll set the alarm off as it's got dual prox. if someone stands within a foot of the door it'll 'bark' at them to let them know they're too close.
If you want bells and whistles then get a clifford one. remote start. remote window opening and closing. dual prox. Blackjax - antihijack, voice module. operate anything in the car from the remote. lights, boot release, wipers, horn, anything you want.
if you want a quality reliable alarm then go for a toad ai606. you can still do the lights and boot release.
