What record are we actually trying to break here?I gather up in the Netherlands they had 160 or so MR2's in a row.
Think we've got that one sorted. But on the Guinness website I can't actually find any mention for longest 'parade'* of cars. They have longest parades by fiats, bmw's ferraris, mazdas etc, oddly no Toyota, and all of them look to have had considerably fewer cars that we might arrive in on Sunday, and we're limiting ourselves to single model, not just single make. Does anyone know what the longest organised parade of cars of any sort is? Could we take that one? 
Is someone official coming to ratify it?
I've done some crazy things to pass a Sunday, but this one takes some beating.
