Have I been ripped off?

[llewdaert]

I purchased a 2011 ec 300 and i think I have been ripped off,
The vin is either
VTREC3000G0160943
or
VTREC3000C0160943
its hard to tell ,it has Nambotin plastics
the vin checker says 2016 model or 2012 model
the frame looks like an older model[now that I am having increased scrutiny]
its rectangular section -with no cutouts down near the swingarm.
The engine number is EC300506013599. Any suggestions on what I got?
Thanks
James
