Was it a ban, finances or choice, I wonder?...
I totalled it, as in total write-off, after an argument with a stone wall. We bought it in 2005 at 18 months old, the garage said the cost of bodywork repair would greatly exceed its present value at 13 years old, the insurance company wrote it off and sent me a cheque.
That incident was portentous: since we moved to this apartment with very good transport links and shops within walking distance, the car was sitting there idle in our indoor parking space almost all the time, we had to buy a trickle charger to keep the battery good. I'm really glad to be out of the game now, not missing it at all.
However, I think it would be goodbye for my 250 mile trips to North Wales and elsewhere, for I rely on the car to store additional camping equipment, clean clolthes, etc
That's one of the great things about backpacking: the confidence of self-sufficiency with everything you need in your pack, no need to store superfluous things. I guess you've considered that option. With the single exception of socks we never carry spare clothes.
To get a rough idea using a 3-day return trip, a quick check in the journey planner shows a return fare from London Euston to Llandudno Junction of £59.35 with a senior railcard, that's the bulk of the journey.
Edit: the journey planner behaved differently this time, it showed the outward and return fares separately - the total fare is 59.35, not 30.65 as originally stated.
