It is the owner responsibility to keep in safe! I do! OK I know a bit about cars, but if I'm not sure I get it looked at by someone! My family go in that car too, so moraly I think I have no choice but to keep it to the best standard I can! You wouln't take you child in a car that you thought had dodgy brakes would you?

Old car's don't have many of the safely features many new ones do so you you have to make sure that the ones that the do have work at least as well as designed!
