So I decided to try one of those fast lube places on my way to work (I haven't had a chance to go to my normal mechanic) and they charged me a $3.99 "Skid Plate Removal" fee. When I questioned them, they said most new cars require the skid plate to be removed in order to change the oil. I have a stock 2004 WRX wagon. Is this legit? They seem to try to get you with the cheap base price but get you with these add-ons (like +$6 for the Mobil 1 oil filter).
