What exactly did the letter say?
My dealer sends out letters that basically say, "Hey based on a guestimate we think you may need service about now". For a new car with no record they probably send it out at some average number like
7500. Once you go in they prorate that by your actual observed mileage, or maybe a six month calendar period - if that's not already factored by the mileage minder.Just what everyone says - when the minder says go, best to go. You can check the manual for what is scheduled, and that's a good thing to do because otherwise dealer may try to load up a bunch of crap. My dealer does. I even give them a little slack, another $50 or so on a minor checkup once a year keeps them happy and I guess it's a cost of doing business, but much more than that and I tell them to please stick to the schedule and I'll just risk it. Small risk there while the car is under warranty.
