I had a mk2 Consul some years back (1971) ... burnt a hole in a piston and on the money I was on .. 21 Guineas a week before paying for food & accomodation .. I had no cash to fix it, but I knew I could trade it in and get something on the "never never" using it as a deposit .. if it was OK - which it wasn't ..

.... so I drove it down from Yorkshire to Wiltshire with the blown piston ... stopping at a service station every 40 minutes and buying waste oil which I just filled it with .. then drove on .. complete with a very nice cloud of blue smoke behind me. I reckon a gallon of waste lasted 40 miles ..

When I got to Wilts I got some tractor gearbox oil of a farmer, filled it up then parked it up in a layby about 1/2 a mile from a place that sold motors. Next day I started it up drove it onto the forecourt with an extremely light throttle, and as it was still cold it was not producing smoke at all.
Had a poke around a neat but cheap Austin 1300 .. when the owner came out to have a chat I offered him the keys to the Consul and suggested he take it for a drive and tell me how much he'd give me for it in PX .. his answer was nah .. he saw me drive it in, it looked reasonable .. he was happy to take it as deposit .... I did the deal, drove the 1300 round to home .. said good bye to my parents and left for Yorkshire PDQ !!
Always wondered what he said when he actually tried to run it .....
the things we did when young ....
