That sounds to me like a way the dealer can make a nice profit from those services. After I bought my car they me and my wife to a small office where a older trusty looking man sat. He talked a good while about this service. All was fine till he quoted the price. I do my own oil changes so I know it's done right. I buy my oil filters from the toyota dealer. I will switch to the toyota 0w-20 oil at my first 5000 mile oil change. I wonder if that service included toyota's full synthetic oil.

You can also buy your oil and filter from any auto store and pay a small labor fee to have it change at any oil change place. I take my car to walmart where I bought the lifetime tire rotate and balance service. They seem to do a good job and the wife loves to shop while there working on the car. Me, I head off to the electronic department to see whats new.

I'm not sure how much 4 years of air filters and AC filters would cost. I thought most air filters go about 30,000 miles till there replace. The way I drive, that would be one filter every 2 years. I always buy toyota replacement filters as there made just for this particular engine. Purolator used to make the toyota filters but im now sure these last few years.
