Hello there, new member so please be gentle.

I'm looking to by an MG ZT V8 in a few months time and one of the things concerning me is security. ( My previous car was stolen . )
I know the car comes with a cat 1 alarm but is it still any good by today's standards and would you recommend a particular alarm system I could get fitted.
Apart from very angry dogs is there any other security measures worth considering.

Thanks
