Having made my decision (pretty quickly in the end) that Saxo will go to the eternal car park via a charitable donation, and that I will probably subscribe to the local 'car club' on the basis that they have several cars in reasonable walking distance, and that I can use public transport or taxis for local stuff, I feel strangely liberated.  Almost, it feels, as liberated as when I first owned a car and could go where I wanted, when I wanted to get there.

Of course there are implications of not having a car - but nothing insurmountable.
