Thanks, Paul and Nan.
There are no kids in the scenario, Nan, so that one won't suit the circumstances. But anyway there's no concluding to do because it never gets to the point of the car being examined by a professional, so that aspect isn't something that matters terribly.
Your other idea sounds very workable, though and I think I certainly have enough ideas to be able to work something out. Thanks again for the help!
Paul, many thanks for doing all that web checking. You're a star! Most helpful.
I think, on reflection you're probably right that the unpredictablity of the toffee solution makes it dodgy. I don't want the car running for three hours and forty miles before it hacks out its last gasp, after all.
