It has nothing to do with a smart mechanic and a dumb mechanic.
They just try to pull the covers over peoples eyes so they dont see the anal rapeage that is about to come.
They would of probably swapped that ****** out for a rebuilt one, taken your good one out and waited for the poor guy with a broken ****** to come in so they can make double off of it.
There is no honesty or good people left in this world, thats why im glad I have a HUGE family full of doctors, mechanics, lawyers and yadda yadda.... I dont have to deal with that bullshit
