Need some recommendations on what brand, type, model, ect. of alarm system to get for my 87. Not really looking for the kind that talks when you get to close. Just something that will sound if someone bust my windows(including the rear window) or opens the door while its locked. Would like to have keyless entry as well. One last thing would be something that is not to hard to install and comes with clear and to the point intructions. Thanks for any help.
