my advice is; don't take matters into your own hands. find you a decent cop/detective that will sympathize with you and understand what you are going through. you'll get little regard in CA since most tuners are looked down upon as nuisances (like these cats that stole your shit)
i had 2 integras' stolen from me when i was 19/20 yrs old. its a terrible feeling but i moved on from it. may wanna change it up to something that's less appealing to steal. i don't really hear about 240s' getting stolen these days. you'll figure it out bro
