Some have suggested you call out the AA or RAC, join and get them to rescue you.
I’m not a member of either organization – but I don’t think it works like that, otherwise why join at all? All members could save themselves the annual membership fee, only paying once they have a breakdown. The AA/RAC would be severely out of pocket, only receiving membership money from motorists who had broken down, and for this money they would have attended at least one call out.
The AA/RAC might come to your aid, but I would expect them to want loads of money and you to join.
My advice would be to call out a local garage (and possibly get ripped off).
In my 30+ years of driving, without being in a breakdown organization, I have never had a breakdown I couldn’t sort myself.
If the worst came to the worst and I was charged £1,000 to get back home – I would still be up of the deal of paying an annual fee of £40.
