What new alarm...?

[tweety]

Been told by my insurance company (Directline) that I now need to have a Cat 1 alarm fitted to the Griff or else I'm not covered for theft of or from. Didn't need to have one last year and apparently the standard system is too old to qualify. So what to fit, Clifford, Toad, ?? and where to get it done on the South Coast? The car is only used weekends and sunny days, so it's mainly to keep the insurance company happy. All advice and recommendations would be greatly appreciated.

Cheers, Al.
