Doing it myself!

A couple of months ago, during an oil change appointment, the mechanic popped out my engine and cabin air filters and asked me if I'd like them to be replaced. I said, "No, thank you." and thought to myself - did he seriously just pop those out and back in again? Well, letting me see THAT was a mistake! I paid a fraction of the cost to purchase them online, and it just took me about 10 minutes to replace the air filters in the cabin and in the engine of my car. Another vehicle maintenance expense avoided!
