From hard-won experience, @Evell is right - once you've got significant sunk costs in tax and insurance, it's hard not to throw bad money after good once a 'cheap' car tears its clutch to bits or fails its MOT. The next price bracket up is probably the place to be for reliable cars which still don't leave you with a valuable asset parked on the street. I'm also SE and got on well with Blackheath Motor Company last year, honest and straightforward to deal with and gave me a fair trade-in.
