The attractive option still owes an account of its ordinary upkeep.

Anything being proposed to you is presented at its best moment. The photograph is of the finished thing on a good day, and the running costs, the servicing, the hours per week it will claim, are not in the picture because nobody selling anything volunteers them. That is not dishonest; it is how proposals are made. But a decision taken on the strength of the best day will keep meeting the ordinary ones.

Ask for the boring numbers before you agree: what it costs to keep going, who does that, how often. If nobody can answer, treat the silence as information rather than a detail still to be worked out.
