what "approved" alarm should I go for? I need some advice quick. My new car (R33 S2 4 Door) will be registerd next week and I am looking for some guidance on what alarm to go for. Shannons and Justcars have stated that I must have an "approved" alarm system fitted otherwise - no cover. The brands that I have looked into so ar are: Antitheft, Cobra, Flashpoint, Mongoose and Rhino. Can anyone steeer me in the right direction. I expect to pay between $450 - $600 fitted and prefer 3 point immobilisation.
