Hey peeps

Not sure if this is in the right section...just want some advice and views really.

I've recently bought my first car...a 1997 MK4 Fiesta 1.25

The car has got no alarm on it and I am keen to have one installed...has anyone had this done? Got an idea of the cost (for a specialist company to do it) and if it would mean making any 'hole's etc?

This one is only an idea really but I would like to have a central locking system on it too...again anyone had this done? how much would it cost?

Thanks
