I don't have to know the exact mileage when I dropped it off to work out the extra mileage that had been done. Last service mileage was 41461, this service mileage was 51651. So total mileage since last service is 51651 - 41641 = 10010. I know for a fact that from last service to the day I dropped the car off I have done 9800 miles. Therefore the difference is 10010 - 9800 = 210 miles.
I admit the cost to fix the steering wheel is an assumption on my part. But any repairs done by dealership is expensive nevertheless. I have no reason to make this up. I only found out about the mileage difference by chance as the mileage on the invoice does not match the actual mileage. In addition, the lad at the reception was trying to brush me off and being very evasive when I first raise the problem to him when the manager was not there.
