It would have been fun to take it to some other dealer for that 6000-mile oil change. Then the original dealer would see it on the service history (I am assuming) and realize the money they lost out on.My Dad went in for service when the vehicle had 6,000 miles on it and asked for an oil change. The dealer refused and said it didn't need to be done until 1yr or 12,000 miles. My Dad said he would gladly pay for the oil change. The dealer again refused and said to come back at 1 year or 12,000 miles.
