Sean’s Car repair

Hi I'm Sean and this is the second time now I've been taken for an idiot on a car, my first car engine was beyond repair so brought another car for £1500 3 weeks ago only to be told from a garage that it needs a new timing chain kit fitting and not advisable to be driven, I need car for work as I work 12 miles away from home, so now I'm dependent on trying to get lifts to work and back. I also need my car to see my son that lives 190 miles away. I'm struggling with money as it is and can't afford to get the car fixed and can't afford to get rid and get another car
