Paranoia will destroy ya. Your neighbors, friends, mechanics, relatives insurance company employees, etc. know your cars and where you live. Order parts? No secrets there about what you got. Get good insurance, join the NRA with license and training, alarm and camera everything and hope for the best. Meanwhile, enjoy the forum discussion and knowledge.
It would good to know the names and talk with these people at the conventions and not have to try to guess who they are.
This is a great to site to have and read.
