Mod Leak?

I've been looking at some S13's people have been making recently, and I'm starting to notice some odd looking stuff. I won't say any names at this point, but some of these s13's coming out have deadly similar parts to my s13. By that I mean that the polygon's match up perfectly, and the detailing looks exactly the same. Looking closer, I notice that if indeed one of my s13's was leaked out, it would've been one of my older ones, possibly before it was an Onevia. Pieces like the Rear Bumper, Sideskirts, Rollcage, engine parts and even the steering wheel are starting to appear on some other peoples cars, or some mysterious very accuritaly duplicated look-alikes. There is only a handful of people that have I have personally given any of my cars to, and each one was told specifically NOT to share it. If it was you, do tell on MSN or the shoutbox and get your slap to the face. I won't be suprised if the whole car is used in someones next mod.
