How much for alarm and fittings???

[BenWall]

Hi, I have one of the old clios and that was broken into last night and they took everything apart from the seats and stearing wheel.

So for my new clio I have just puchased (not a new one, but the one w/o alarm) I need to but a alarm me thinks, as this one has a CD Changer control panal on view and so on. so How much would it be to buy and fit???

alarm around the £50-70 mark

Thanks in advance
