If you've sold something(and you knew) that WASN'T what YOU said it was what you expect him to DO?
SAY he's been having a rebuild on the engine and got it back together(now) and only NOW finds out that the turbo dont fit!
MAYBE THATS WHY HE NEVER LEFT FEED BACK TILL HE MADE SURE IT WAS OK!
@ the end of the day it's YOUR call
