Concept 300's are pieces of shit im sorry to say,

My mate had an Astra SRi, he left it parked on the road for a few months because he wasn't driving it, alarm never worked after.......

It seems almost every alarm problem on here thats a clifford stems back to it being a concept 300.

As said, get a Toad, ive got one, never had any problems and neither has anyone else i know with one
