Instructions:City Car Club is a car share scheme which has cars to use in London, Bristol, Bath, Reading, Poole, Edinburgh, Brighton, Norwich, Portsmouth and Camberley.
Ordinarily you pay a one-off joining fee of £75, an then there are no recurring subscription fees - you just pay as you go by the hour and for mileage.
Abel & Cole have a discount code on their web site to get £50 off (66% discount!) and you also get 5 hours of free driving thrown in. I was about to sign up at the full price, then googled this code and got a whopping great discount!
Excellent for those that don't have a car, or require irregular access to a 2nd car.
