As you have no back up its worthwhile your considering full AA/RACetc cover- make sure it includes getting you and your vehicle home should your car breakdown and the mechanic is unable to sort the problem under the basic cover of roadside assistance or your car not starting at home. I get my cover by saving my supermarket points each year, so feel it's not costing me anything. I also recommend getting a sat nav. I hope you find a super little car and have fun driving - good luck.
