It's seems a theme on here that dealer don't like roadside traders and how they try and get out of there responsibilities if a fault occurs with a car. Then we have a dealer wanting / expecting a customer to wait for two day for a fault to be looked at on a car he purchased that day. Then it's seems like the dealer wants the customer to foot the bill for using decent parts instead of cheap parts. Lets be fair, how do we think this customer is feeling at the moment about his new car and the 'experience' of buying it?? My advice is pay the bill and keep the customer happy, forget £13.99 coil packs and put it down to experience. If he had had the car 20 days it's different story. Once he had phoned maybe the best course of action would be to get the car back, lend him a car, sort the problem and take the car back to him. That way you are in control of the problem. None of us like spending money but faults occur on cars, sometimes it will happen on the day of purchase. Moaning about the less desirable elements of the motor trade and then acting like one doesn't help anyone
