The potential savings make it sensible. According to the RAC, it now costs more than £5,000 a year to run an average car - and that's without taking into account the average cost of a parking permit (around £90 for many boroughs), and the fact that Londoners pay more for insurance than drivers in other areas of the country.
Nicola Davies, 30, from Carshalton Beeches, joined a club at a new housing development in Wallington, Surrey, where she works as a resources manager, after her Nissan Micra was written off six months ago.
"My car cost me over £210 a month to run, but now I use the car club about three or four times a week and comparatively I spend about £100 a month," she says.
"I'm a member of a ban, so most of the time I use it to go to gigs or rehearsals straight after work. Having the car on hand, and by the office, works out really well for me. They don't charge you between 11pm and 7am, so I can take the car home and drive it back it back to work. I also use it for days out of town. I can't fault it."
So far the London city clubs have just over 80 members, but demand is growing all the time. "We are getting quite a few queries from people about the possibility of opening a club in their neighbourhood," says Sarah Stables of Smart Moves, the company that launched the clubs. "It is a new concept for London, but it looks like it is going to really catch on."
