CAT 1 Alarm - Price???

[cj.ok]

I'm currently looking to buy a new Impreza via an importer.... the only difference from standard UK car being that a CAT 1 Alarm isn't standard. To install a CAT 1 to the same standard as a UK car i'm being asked for £399.... is this a fair price or am i being ripped off?

Cheers!
