Sorry if this has been asked before but i cant find it in the archives.
Just bought a '99 S1. How can i tell if the alarm/immobiliser is the Cat 1 equivalent or just a bog standard one. Its a Lotus fitted Cobra but thats all i know so far.
I think you're right and there may be some cars floating around without the Cobra 6422, so check before you arrange your insurance or you may not be covered for theft!
