KnK offered me a full mechanical overhall package that would , almost, guarantee an MOT pass, I think they said it would be about £1000.
They explained that US buses were often mechanically neglegected, and so rather than muck about they would strip and go through the lot, new brakes, regreased bearings, cv joints, full engine service etc etc. To do this they simply offer a flat price.
Me being a tight sod, and not entirely useless in a workshop, decided to take the bus at risk and take it 'as is'.
I replaced the front pads, bolted a horn on, rewired lights to UK spec, replaced one brake hose and I was straight through my mot, under a week from collection.
That said, it 'could' have been a shed. I was chuffed.
