My cousins ex boyfriend had a Civic SI with tons of mods done to it, TV's the works. IE totaly pointless. Anyway one of his "friends" probably stole it and brought it to New Haven, the cops found the body shell on a nice crappy street. Its like the plane that got stripped in Lord of War. Those people are like ants they swarm over something like that and take every bolt. Then your nice $5k brake kit gets sold for $500, and the $1k carbon fiber hood gets slapped on some $500 POS civic with miss matching fenders.
I never lock my cars, no one bothers them.
