You really have to be careful with that kind of stuff and make sure you read everything thoroughly.the fact that the title and the description says different engines should have been enough.
My computer isnt upoaing the motor shots or this description thats says z6 or y7?Yeah it took my computer a sec to i walked away and came back and saw it and was like wow he posted an engine pic and you still thought it was a bseries.
He calls it a b series in the title but if you read the add he says its a z6 and posts an engine pic of a y7 dudes obviosly a piece of s**t, but you should have read all that and seen straight throught it if not the pic. the fact that the title and the description says different engines should have been enough.
