back in 2007 i was helping a friend get an engine change done in wrexham , and then driving it home to epsom, got it running, was awesome , petrol lines plumbed in backwards :/ , kept cutting out, but soldiered on until the M6........ and roadworks, and no hard shoulder, and 2 lanes, and rush hour, we waited for an hour for recovery (front end buried in the cones) with blaring horns / shouted abuse and torrential rain... LOL
