The remark was made a little 'tongue in cheek' Alan, but it is an interesting thought non-the-less!
While I would be very happy to cash-in a non-performing ISA in order to give a home to a well-sorted car like yours, it would hardly be a good one in the accepted sense.
The car would certainly be well cared for, yes, but there would be no heated, car-pet-ed garage waiting. I'm afraid that it would need to live outside year round as do our other cars. Of which we currently have three, so we, too, would also need to consolidate if ever this should become a serious possibility.
In that event, I might start looking into renting a garage locally. Mmm ...
Regards, John.
