Hi folks id like some advice on whether I should use a welder here or not. I want to buy this ford escort estate so much, as it is being sold cheap at £250 having only 25K mileage as it was purchased off a previous owner whose wife used to drive it about. Having seen it there is a rust patch which is becoming a little hole 2 inches in diameter where the back windscreen wiper sits...Can I get this welded or should I forget about buying the car? The MOT is about to run out too, and I dont know whether there are other hidden faults too but I have test driven it and its as smooth as you like.
