30k + The rubber under the front bumper

[Supairman]

Hi everybody,

First of all congratulations and thanks to all the members for this great forum. Two weeks ago I purchased a used 2008 Yaris Sedan (4spd-auto) at 28k miles.

The dealer sticker on the car says 29500 for the next maintenance instead of 30k. Before buying the car I took it to the same Toyota dealer who was doing the maintenance work for this car since its purchase. He inspected and said "It is perfect but just don't forget the 30k maintenance" and when asked he said it is going to cost 350+tax something. It doesn't really make sense since 30k maintenance according to the manual just includes oil+oil filter+air filter changes with tire rotation.

I know tire rotation can be done for free in some places and oil change for about 25$ for conventional oil. My car has synthetic so I am not perfectly sure about it.

The main question could be : Do I have to go to a Toyota Dealer for the maintenance to keep my car under warranty? What if I get the maintenance work done in different places but keep the receipts?

And also today I noticed that the rubber under the front bumper ( I assume that is called a wind deflector but I am an aerospace engineer myself and I don't really think it makes a big difference in the drag force on the car unless it is hanging down like it is now :) ) has lost two of its screws in the middle and I think I can glue it or tape it since it has ripped of the screws with the holes. Do you have any suggestions/advices/warnings?

Thanks for your replies!!!
